B-Raf proto-oncogene serine/threonine-protein kinase (BRAF), also known as Serine/threonine-protein kinase B-raf, Proto-oncogene B-Raf, p94, v-Raf murine sarcoma viral oncogene homolog B1, is a member of the RAF family. BRAF is one of the key factors in mitogen-activated protein kinase (MAPK) signaling pathway, which is activated by members of the Ras family upon growth factor-induced stimulation. BRAF controls and regulates numerous essential cellular mechanisms including cell proliferation, differentiation, development, survival, apoptosis and secretion.1-2 In contrast to the majority of oncogenic fusion kinases such as ALK, ROS1, NTRK1 and RET that are receptor tyrosine kinases, BRAF encodes a non-receptor serine/threonine kinase, placing its normal protein localization within the cytoplasm rather than associated with the plasma membrane.3BRAF is mutated at a high frequency in several cancers, including non-Hodgkin lymphoma, colorectal cancer, malignant melanoma, thyroid carcinoma, nonsmall cell lung carcinoma, and adenocarcinoma of lung.
