Catalytic activity:ATP + a protein = ADP + a phosphoprotein. ,Domain:A PH-like domain is involved in phosphatidylinositol phosphate binding. ,enzyme regulation:Stimulated rapidly but transiently by both cell fibronectin interactions , as well as by insulin , in a PI3-K-dependent manner , likely via the binding of PtdIns (3 ,4 ,5) P3 with a PH-like domain of ILK. ,Function: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. ,PTM:Autophosphorylated on serine residues. ,similarity:Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. ,similarity:Contains 1 protein kinase domain. ,similarity:Contains 5 ANK repeats. ,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 (via ANK repeats) with LIMS1 and LIMS2. Interacts with parvins and probably TGFB1I1. ,tissue specificity:Highly expressed in heart followed by skeletal muscle , pancreas and kidney. Weakly expressed in placenta , lung and liver. ,
