C-Raf (C-Terminus) (raf1a) Antibody – Rabbit Polyclonal

The Ras-Raf-MAP kinase signaling pathway is involved in control of cell proliferation and differentiation. The Raf kinase family includes A-Raf, BRaf, 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. EGF receptor activation leads to phosphorylation of Ser-471, which is critical for C-Raf kinase activity and is required for interaction with MEK. In B-Raf, the corresponding conserved site is Ser-578, and mutation of this residue to alanine produces an inactivate kinase. Thus, this Raf phosphorylation site may be critical for kinase activity and may be important for MEK binding and activation.

Small volumes of anti-raf1a antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
