Detection of Human/Mouse/Rat RKIP by Western Blot. Western blot shows lysates of HUVEC human umbilical vein endothelial cells and A172 human glioblastoma cell line. PVDF membrane was probed with 0.2 µg/mL of Human/Mouse/Rat RKIP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4538) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for RKIP at approximately 23 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

Raf kinase inhibitor protein (RKIP) is a member of the phosphatidylethanolamine-binding protein (PEBP) family, and modulates the activation of several signal transduction cascades. By binding the MAP3K Raf-1, unphosphorylated RKIP inhibits activation of the MAP2K MEK. PKC-phosphorylated RKIP dissociates from Raf‑1 and inhibits GRK2, resulting in sustained G-protein signaling. Expressed in many tissues, RKIP is implicated in the regulation of such physiological processes as membrane biosynthesis, spermatogenesis, neural development, and metastasis suppression.
