FUNCTION: SwissProt: Q13418 # Receptor-proximal protein kinase regulating integrin- mediated signal transduction. May act as a mediator of inside-out integrin signaling. Focal adhesion protein part of the complex ILK-PINCH. This complex is considered to be one of the convergence points of integrin- and growth factor-signaling pathway. Could be implicated in mediating cell architecture, adhesion to integrin substrates and anchorage-dependent growth in epithelial cells. Phosphorylates beta-1 and beta-3 integrin subunit on serine and threonine residues, but also AKT1 and GSK3B.
SIZE: 452 amino acids; 51419 Da
SUBUNIT: Interacts with cytoplasmic domain of beta 1 subunit of integrin. Could also interacts with beta 2, beta 3 and/or beta 5 subunit of integrin. Interacts with LIMS1, LIMS2, parvins and probably TGFB1I1.
SUBCELLULAR LOCATION: Cell junction, focal adhesion; Cytoplasmic side.
TISSUE SPECIFICITY: Highly expressed in heart followed by skeletal muscle, pancreas and kidney. Weakly expressed in placenta, lung and liver.DOMAIN:SwissProt: Q13418 A PH-like domain is involved in phosphatidylinositol phosphate binding.
PTM: Autophosphorylated on serine residues.
SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. & Contains 3 ANK repeats. & Contains 1 protein kinase domain.
