| Gene Target | Biological Function | Application as a Biomarker |
|---|---|---|
| B-Raf proto-oncogene, serine/threonine kinase (BRAF) | The B-Raf proto-oncogene, serine/threonine kinase (BRAF) encodes a cytoplasmic serine/threonine protein kinase that is a member of the RAF kinase family. BRAF functions as part of the RAS-RAF-MEK-ERK signaling pathway (also known as the MAPK/ERK pathway), which transduces signals from the cell membrane to the nucleus in response to growth factors and other extracellular stimuli. Upon activation by RAS proteins, BRAF phosphorylates and activates MEK1 and MEK2, which in turn activate ERK1 and ERK2. This signaling cascade regulates key cellular processes, including proliferation, differentiation, and survival. Mutations in BRAF, particularly the V600E substitution, result in constitutive kinase activity and aberrant MAPK pathway activation. | BRAF is widely used as a molecular biomarker in oncology. Detection of activating BRAF mutations, most notably the V600E mutation, is applied in the diagnosis, prognosis, and therapeutic stratification of several cancers, including melanoma, colorectal cancer, thyroid carcinoma, and non-small cell lung cancer. The presence of BRAF V600E mutation can predict response to targeted therapies with BRAF inhibitors and is used to guide treatment decisions. Additionally, BRAF mutation status is utilized in distinguishing between different tumor types and subtypes. |
| HRas proto-oncogene, GTPase (HRAS) | HRas proto-oncogene, GTPase (HRAS) encodes a small GTPase protein that is a member of the Ras superfamily. HRAS functions as a molecular switch in signal transduction pathways, cycling between an active GTP-bound state and an inactive GDP-bound state. Upon activation by extracellular signals such as growth factors, HRAS transduces signals from cell surface receptors to intracellular effectors, regulating key cellular processes including proliferation, differentiation, and survival. HRAS is involved in the MAPK/ERK signaling pathway and plays a critical role in normal cell growth and development. | Mutations in HRAS, particularly activating point mutations, have been identified in various human cancers, including bladder cancer, head and neck squamous cell carcinoma, and others. Detection of HRAS mutations or overexpression can be used to characterize certain tumor types and may assist in diagnosis, prognosis, and monitoring of disease progression. HRAS mutation status is also investigated in the context of rare congenital disorders such as Costello syndrome, where germline HRAS mutations are diagnostic. |
| KRAS proto-oncogene, GTPase (KRAS) | KRAS (Kirsten rat sarcoma viral oncogene homolog) encodes a small GTPase that functions as a molecular switch in cell signaling pathways. It cycles between an active GTP-bound state and an inactive GDP-bound state. KRAS is a key component of the RAS/MAPK signaling cascade, regulating cellular processes such as proliferation, differentiation, and survival in response to extracellular signals. Upon activation by upstream stimuli, such as growth factor receptors, KRAS transmits signals to downstream effectors, influencing gene expression and cellular outcomes. Mutations in KRAS can impair its intrinsic GTPase activity, resulting in constitutive activation and aberrant signaling. | KRAS is widely used as a biomarker in oncology, particularly in the context of solid tumors such as colorectal, lung, and pancreatic cancers. The presence of specific KRAS mutations is associated with resistance to certain targeted therapies, such as anti-EGFR monoclonal antibodies in colorectal cancer. KRAS mutation status is routinely assessed to guide therapeutic decision-making and predict response to treatment. Additionally, KRAS mutations are used in molecular diagnostics for disease classification and may serve as indicators of prognosis in various malignancies. |
| Raf-1 proto-oncogene, serine/threonine kinase (RAF1) | RAF1 (Raf-1 proto-oncogene, serine/threonine kinase) encodes a serine/threonine-specific protein kinase that is a critical component of the RAS-RAF-MEK-ERK signaling cascade, also known as the MAPK/ERK pathway. Upon activation by RAS GTPases, RAF1 phosphorylates and activates MEK1/2, which in turn phosphorylates ERK1/2. This pathway regulates a variety of cellular processes including cell proliferation, differentiation, survival, and apoptosis. RAF1 activity is tightly regulated through multiple mechanisms, including phosphorylation, protein-protein interactions, and subcellular localization. Dysregulation of RAF1 signaling has been implicated in oncogenesis and developmental disorders. | RAF1 has been studied as a biomarker primarily in the context of cancer and certain developmental syndromes. Alterations in RAF1, including mutations, overexpression, or abnormal activation, have been observed in several malignancies such as melanoma, lung, and colorectal cancers. RAF1 mutations are also associated with RASopathies, such as Noonan syndrome. Assessment of RAF1 status may be used in research and clinical settings to characterize tumor subtypes, inform prognosis, or guide therapeutic decisions, particularly when RAF1 or its pathway components are considered as potential targets for intervention. |
| SOS Ras/Rac guanine nucleotide exchange factor 1 (SOS1) | SOS Ras/Rac guanine nucleotide exchange factor 1 (SOS1) is a guanine nucleotide exchange factor (GEF) that primarily activates members of the RAS family of small GTPases. SOS1 facilitates the exchange of GDP for GTP on RAS proteins, thereby converting them from an inactive to an active state. This activation initiates downstream signaling cascades, most notably the RAS-RAF-MEK-ERK (MAPK) pathway, which regulates diverse cellular processes such as proliferation, differentiation, and survival. SOS1 is also involved in activating RAC GTPases, contributing to cytoskeletal organization and cell migration. SOS1 activity is tightly regulated by interactions with adaptor proteins, such as GRB2, and by membrane localization in response to receptor tyrosine kinase signaling. | SOS1 has been investigated as a biomarker in the context of certain diseases, particularly cancers. Alterations in SOS1 expression or function have been reported in various malignancies, where they may correlate with aberrant RAS pathway activation. Mutations in SOS1 are also associated with developmental disorders such as Noonan syndrome. In research and clinical studies, assessment of SOS1 gene mutations, expression levels, or protein activity may provide information relevant to disease characterization, prognosis, or therapeutic response, especially in conditions involving dysregulated RAS signaling. |
| discoidin domain receptor tyrosine kinase 2 (DDR2) | Discoidin domain receptor tyrosine kinase 2 (DDR2) is a member of the discoidin domain receptor family of receptor tyrosine kinases. DDR2 is activated by binding to fibrillar collagens, particularly types I and III, in the extracellular matrix. Upon ligand binding, DDR2 undergoes autophosphorylation and initiates downstream signaling cascades that regulate cellular processes such as proliferation, differentiation, migration, and extracellular matrix remodeling. DDR2 is expressed in various cell types including fibroblasts, chondrocytes, and certain epithelial cells. It plays a role in tissue development, wound healing, and maintenance of connective tissue integrity. Aberrant DDR2 signaling has been associated with pathological processes such as fibrosis and tumor progression. | DDR2 has been investigated as a biomarker in several contexts, particularly in oncology and fibrotic diseases. In cancer, altered DDR2 expression or mutations have been reported in non-small cell lung carcinoma, breast cancer, and other tumor types, where they may be associated with disease progression, metastasis, or response to targeted therapies. In fibrotic diseases, such as idiopathic pulmonary fibrosis, increased DDR2 expression has been observed in affected tissues. DDR2 status has been explored in research studies for its potential to inform diagnosis, prognosis, and therapeutic response in these conditions. |
| mitogen-activated protein kinase kinase 1 (MAP2K1) | Mitogen-activated protein kinase kinase 1 (MAP2K1), also known as MEK1, is a dual-specificity protein kinase that plays a central role in the RAS-RAF-MEK-ERK signaling pathway. MAP2K1 specifically phosphorylates and activates ERK1 and ERK2 (extracellular signal-regulated kinases), which subsequently regulate various cellular processes including proliferation, differentiation, survival, and gene expression. Activation of MAP2K1 is typically triggered by upstream signals such as growth factors, cytokines, and mitogens, leading to its phosphorylation by RAF kinases. The MAPK/ERK pathway, in which MAP2K1 is a key component, is highly conserved and critical for normal cellular function as well as development. | MAP2K1 has been applied as a biomarker primarily in oncology, particularly in the context of cancers with aberrant activation of the MAPK/ERK pathway. Somatic mutations in MAP2K1 have been identified in various malignancies, including melanoma, non-small cell lung cancer, and certain hematologic cancers. Detection of MAP2K1 mutations or altered expression levels can provide information on tumor biology, help identify candidates for targeted therapies (such as MEK inhibitors), and may be used to monitor response to treatment. Additionally, MAP2K1 status is sometimes assessed in the characterization of developmental disorders with RASopathies, a group of syndromes caused by mutations in the RAS/MAPK pathway. |
| mitogen-activated protein kinase kinase 2 (MAP2K2) | Mitogen-activated protein kinase kinase 2 (MAP2K2), also known as MEK2, is a dual-specificity protein kinase that plays a central role in the MAPK/ERK signaling pathway. MAP2K2 phosphorylates and activates ERK1 and ERK2 (MAPK3 and MAPK1), which are involved in the regulation of various cellular processes, including proliferation, differentiation, and survival. Activation of MAP2K2 is typically mediated by upstream kinases such as RAF in response to extracellular signals like growth factors. The MAPK/ERK pathway is tightly regulated and is critical for normal cellular function. | MAP2K2 has been studied as a biomarker in oncology, particularly in the context of cancers with aberrant MAPK/ERK pathway activation. Alterations in MAP2K2, including mutations or changes in expression, have been associated with certain malignancies. Measurement of MAP2K2 status or activity has been explored for its potential to inform diagnosis, prognosis, and therapeutic response, especially in relation to targeted therapies that inhibit components of the MAPK pathway. |
| protein tyrosine phosphatase non-receptor type 11 (PTPN11) | Protein tyrosine phosphatase non-receptor type 11 (PTPN11) encodes the SHP-2 protein, a cytoplasmic non-receptor protein tyrosine phosphatase. SHP-2 is involved in multiple intracellular signaling pathways that regulate cell growth, differentiation, migration, and survival. It acts as a positive regulator of the RAS/MAPK signaling cascade by dephosphorylating specific phosphotyrosine residues on target proteins. PTPN11 is widely expressed in various tissues and plays a critical role in embryonic development, hematopoiesis, and immune cell function. Germline or somatic mutations in PTPN11 can lead to dysregulated signaling, contributing to developmental disorders and malignancies. | PTPN11 has been studied as a biomarker in several clinical contexts. Somatic mutations in PTPN11 are frequently identified in hematologic malignancies, particularly juvenile myelomonocytic leukemia (JMML), acute myeloid leukemia (AML), and other myeloproliferative disorders. Detection of PTPN11 mutations in tumor samples or peripheral blood can assist in diagnosis, risk stratification, and monitoring of these diseases. Additionally, germline mutations in PTPN11 are associated with Noonan syndrome, and genetic testing for PTPN11 variants is used in the diagnostic evaluation of this condition. |
