Product Details
B-Raf (S446)[C-Raf (S338)/A-Raf (S299)
The Ras-Raf-MAP kinase signaling pathway is involved in control of cell proliferation and differentiation. The Raf kinase family includes A-Raf, B-Raf, and C-Raf. Each family member has three highly conserved regions (CR1-3). The N-terminal CR1 contains the Ras-GTP-binding domain. The CR2 contains a negative regulatory serine residue (C-Raf (S259)/B-Raf(S365)) that may bind 14-3-3 proteins. The CR3 is the catalytic domain that contains phosphorylation sites for Raf-regulating enzymes within two segments, the N-region and the activation segment. Activation of C-Raf involves phosphorylation at many sites including Ser-338, Tyr-341, and multiple catalytic domain sites. In B-Raf, multiple phosphorylation sites have been identified, but their specific roles are uncertain. Phosphorylation of Ser-446 may prime B-Raf for activation, and Ser-446 and/or Ser-447 phosphorylation may be critical for B-Raf biological activity during PC12 differentiation. Ser-579 is required for growth factor activation and kinase activity. Thus, multiple sites of phosphorylation within Rafs may be important for regulation of their activity.

Phospho-B-Raf (Ser-446) synthetic peptide (coupled to KLH) corresponds to amino acids surrounding serine 446 in human B-Raf. This sequence is conserved in B-Rafs from many species, and has high homology to C-Raf (Ser-338) and A-Raf (Ser-299).

Unconjugated
This antibody was cross-adsorbed to phospho-B-Raf (Ser-579) peptide before affinity purification using phospho-B-Raf (Ser-446) peptide. The purified antibody detects a strong band at 95 kDa* and a weaker band at 105 kDa in western blots of human Jurkat or A431 cells treated with Calyculin A. The antibody also detects other phosphorylated proteins at 150 and 200 kDa in calyculin A treated cells.
