GNB2L1 was originally identified as an anchoring protein for protein kinase C beta (PKCbeta), which it stabilises in the active state and anchors to membranes or functional sites. However, evidence has accumulated to support a central role of GNB2L1 in critical biological responses. In addition to binding specifically to the active form of PKCbeta isoforms, GNB2L1 also interacts with several other important signaling proteins including the Src kinase family, integrin beta1, integrin beta2, integrin beta3 and integrin beta5, beta-spectrin and dynamin, RasGAP, the androgen receptor, insulin-like growth factor 1 receptor (IGF-1r), Epstein-Barr virus trans-activator protein BZLF1, p73 and pRB. GNB2L1 is ubiquitously expressed in the tissues of higher mammals and humans including brain, liver, and spleen. Recombinant protein corresponding to aa1-317 from human GNB2L1, fused to His-tag at N-terminal expressed in E. coli.
