Target
RAF1
Molecular classification
Serine/threonine-protein kinase, MAP3 kinase, Enzyme
01

Overview

Mitogen-activated protein kinase C-Raf (RAF1) is a serine/threonine-protein kinase that serves as a critical regulatory link between membrane-associated Ras GTPases and the MAPK/ERK signaling cascade. It is a principal component of the mitogen-activated protein kinase (MAPK) pathway, specifically acting as a MAP3 kinase that initiates the downstream phosphorylation cascade leading to cell proliferation, differentiation, survival, and gene expression. Aberrant RAF1 activation is implicated in various cancers and developmental syndromes, making it an important therapeutic target.
