  • FunctionInvolved in the transduction of mitogenic signals from the cell membrane to the nucleus. Part of the Ras-dependent signaling pathway from receptors to the nucleus. Protects cells from apoptosis mediated by STK3.
  • Tissue specificityIn skeletal muscle, isoform 1 is more abundant than isoform 2.
  • Involvement in diseaseDefects in RAF1 are the cause of Noonan syndrome type 5 (NS5) [MIM:611553]. Noonan syndrome (NS) is a disorder characterized by dysmorphic facial features, short stature, hypertelorism, cardiac anomalies, deafness, motor delay, and a bleeding diathesis. It is a genetically heterogeneous and relatively common syndrome, with an estimated incidence of 1 in 1000-2500 live births.
    Defects in RAF1 are the cause of LEOPARD syndrome type 2 (LEOPARD2) [MIM:611554]. LEOPARD syndrome is an autosomal dominant disorder allelic with Noonan syndrome. The acronym LEOPARD stands for lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormalities of genitalia, retardation of growth, and deafness.
  • Sequence similaritiesBelongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. RAF subfamily.
    Contains 1 phorbol-ester/DAG-type zinc finger.
    Contains 1 protein kinase domain.
    Contains 1 RBD (Ras-binding) domain.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylation at Thr-269 increases its kinase activity. Phosphorylation at Ser-259 induces the interaction with YWHAZ and inactivates kinase activity. Dephosphorylation of Ser-259 by the complex containing protein phosphatase 1, SHOC2 and M-Ras/MRAS relieves inactivation, leading to stimulate RAF1 activity.
  • Cellular localizationCytoplasm. Cell membrane. Colocalizes with RGS14 and BRAF in both the cytoplasm and membranes.
