BRAF

Serine/threonine kinase; V600E mutation constitutively activates MEK-ERK without RAS input. Mutated in ~50% of melanomas, 60% of papillary thyroid cancers, and 10% of CRC. Combined BRAF+MEK inhibition (dabrafenib+trametinib) is standard of care in V600E-mutant melanoma.

Also known as: BRAF V600E, v-raf murine sarcoma viral oncogene homolog B, BRAF kinase, B-RAF
