  • FunctionAdapter protein that plays a role in the assembling of signaling complexes, being a link between ABL kinases and actin cytoskeleton. Can form complex with ABL1 and CBL, thus promoting ubiquitination and degradation of ABL1 or with AKT1 and PAK1, thus mediating AKT1-mediated activation of PAK1. May play a role in the regulation of pancreatic cell adhesion, possibly by acting on WASF1 phosphorylation, enhancing phosphorylation by ABL1, as well as dephosphorylation by PTPN12 (PubMed:18559503). Isoform 6 increases water and sodium absorption in the intestine and gall-bladder.
  • Tissue specificityAbundantly expressed in heart. In cardiac muscle cells, located in the Z-disks of sarcomere. Also found, but to a lower extent, in small and large intestine, pancreas, thymus, colon, spleen, prostate, testis, brain, ovary and epithelial cells. In the pancreas, mainly expressed in acinar cells, duct cells and all cell types in islets (at protein level). Tends to be down-regulated in pancreatic adenocarcinomas ans metastases.
  • Sequence similaritiesContains 3 SH3 domains.
    Contains 1 SoHo domain.
  • DomainThe first 2 SH3 domains are required for WASF1-binding. All 3 SH3 domains can bind independently to PTPN12.
  • Post-translational
    Ubiquitinated by CBL.
    Dephosphorylated by PTPN12.
  • Cellular localizationCytoplasm, perinuclear region. Apical cell membrane. Cell junction, focal adhesion. Cell projection, lamellipodium. Found at the Z-disk sarcomeres, stress fibers, dense bodies and focal adhesion. In pancreatic acinar cells, localized preferentially to the apical membrane. Colocalized with vinculin and filamentous actin at focal adhesions and lamellipodia of pancreatic cells.
