CC -!- FUNCTION: Receptor-proximal protein kinase regulating integrin-mediated
CC signal transduction. May act as a mediator of inside-out integrin
CC signaling. Focal adhesion protein part of the complex ILK-PINCH. This
CC complex is considered to be one of the convergence points of
CC integrin- and growth factor-signaling pathway. Could be implicated in
CC mediating cell architecture, adhesion to integrin substrates and
CC anchorage-dependent growth in epithelial cells. Regulates cell motility
CC by forming a complex with PARVB. Phosphorylates beta-1 and beta-3
CC integrin subunit on serine and threonine residues, but also AKT1 and
CC GSK3B. {ECO:0000250|UniProtKB:Q13418}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,

CC EC=2.7.11.1; Evidence={ECO:0000250|UniProtKB:Q13418};
CC -!- ACTIVITY REGULATION: Stimulated rapidly but transiently by both cell
CC fibronectin interactions, as well as by insulin, in a PI3-K-dependent
CC manner, likely via the binding of PtdIns(3,4,5)P3 with a PH-like domain
CC of ILK. The protein kinase activity is stimulated by LIMD2.
CC {ECO:0000250|UniProtKB:Q13418}.
CC -!- SUBUNIT: Interacts with the cytoplasmic domain of ITGB1. Could also
CC interact with integrin ITGB2, ITGB3 and/or ITGB5. Interacts (via ANK
CC repeats) with LIMS1 and LIMS2. Interacts with PARVA (via C-terminus)
CC and PARVB; these compete for the same binding site (By similarity).
CC Interacts probably also with TGFB1I1 (By similarity). Interacts (via
CC ANK repeats) with EPHA1 (via SAM domain); stimulated by EFNA1 but
CC independent of the kinase activity of EPHA1 (By similarity). Interacts
CC with FERMT2 (By similarity). Interacts with LIMD2; leading to activate
CC the protein kinase activity. Interacts with PXN/PAXILLIN (via LD motif
CC 4). Interacts with CCDC25 (via cytoplasmic region); initiating the ILK-
CC PARVB cascade to induce cytoskeleton rearrangement and directional
CC migration of cells (By similarity). {ECO:0000250|UniProtKB:O55222,
CC ECO:0000250|UniProtKB:Q13418}.
CC -!- SUBCELLULAR LOCATION: Cell junction, focal adhesion
CC {ECO:0000250|UniProtKB:Q13418}. Cell membrane
CC {ECO:0000250|UniProtKB:Q13418}; Peripheral membrane protein
CC {ECO:0000250|UniProtKB:Q13418}; Cytoplasmic side
CC {ECO:0000250|UniProtKB:Q13418}. Cell projection, lamellipodium
CC {ECO:0000250|UniProtKB:O55222}. Cytoplasm, myofibril, sarcomere
CC {ECO:0000250|UniProtKB:Q13418}.
CC -!- DOMAIN: A PH-like domain is involved in phosphatidylinositol phosphate
CC binding. {ECO:0000250|UniProtKB:Q13418}.
CC -!- PTM: Autophosphorylated on serine residues.
CC {ECO:0000250|UniProtKB:Q13418}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. TKL Ser/Thr
CC protein kinase family. {ECO:0000305}.
