Serine/threonine-protein kinase BRAF (BRAF)

Target
BRAF
Molecular classification
Enzyme, Protein kinase, Serine/threonine kinase
01

Overview

Serine/threonine-protein kinase BRAF (B-Raf) is a key component of the RAS/MAPK signaling pathway, regulating cell division, differentiation, migration, and apoptosis. Mutations, particularly V600E, lead to constitutive activation and are implicated in various cancers, making it an important therapeutic target. Several selective inhibitors have been developed for clinical use.
