AKAP12 Antibody – Rabbit Polyclonal

The A-kinase anchor proteins (AKAPs) are a group of structurally diverse proteins, which have the common function of binding to the regulatory subunit of protein kinase A (PKA) and confining the holoenzyme to discrete locations within the cell. This gene encodes a member of the AKAP family. The encoded protein is expressed in endothelial cells, cultured fibroblasts, and osteosarcoma cells. It associates with protein kinases A and C and phosphatase, and serves as a scaffold protein in signal transduction. This protein and RII PKA colocalize at the cell periphery. This protein is a cell growth-related protein. Antibodies to this protein can be produced by patients with myasthenia gravis. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

AKAP12: a scaffold protein that contains 3 conserved PKA binding motifs. Suppresses podosome formation, inhibits RhoA and Cdc42 activity, and inhibits v-Src-induced oncogenic growth in NIH3T3. May inhibit Src-induced oncogenesis by reestablishing actin-based non-invasive cytoskeletal architecture.
