Background Information

B-Raf proto-oncogene serine/threonine kinase(BRAF), is a protein belonging to the raf/mil family of serine/threonine protein kinases. BRAF plays a role in regulating the MAP kinase/ERKs signaling pathway, which affects cell division, differentiation, and secretion. BRAF is associated with cardiofaciocutaneous syndrome, a disease characterized by heart defects, mental retardation and a distinctive facial appearance. BRAF is also associated with various cancers, including non-Hodgkin lymphoma, colorectal cancer, malignant melanoma, thyroid carcinoma, non-small cell lung carcinoma, and adenocarcinoma of lung. BRAF plays a role in the PD-1/PDL-1 pathway. In some cancers, BRAF is activated by rearrangements that fuse its kinase domain to 5' partner genes and then has different molecular weights (PMID: 23890088).
