Function

[ILK_HUMAN] 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. [LIMS1_HUMAN] Adapter protein in a cytoplasmic complex linking beta-integrins to the actin cytoskeleton, bridges the complex to cell surface receptor tyrosine kinases and growth factor receptors. Involved in the regulation of cell survival, cell proliferation and cell differentiation.

Publication Abstract from PubMed

The heterotrimeric complex between integrin-linked kinase (ILK), PINCH, and parvin is an essential signaling platform, serving as a convergence point for integrin and growth-factor signaling and regulating cell adhesion, spreading, and migration. We report a 1.6-A crystal structure of the ILK ankyrin repeat domain bound to the PINCH1 LIM1 domain, revealing the molecular basis of ILK-PINCH interactions and providing a structural description of this region of ILK. This structure identifies 5 ankyrin repeats in ILK, explains previous deletion mutagenesis data, permits identification of ILK and PINCH1 point mutations that disrupt the interaction, shows how zincs are coordinated by PINCH1 LIM1, and suggests that conformational flexibility and twisting between the 2 zinc fingers within the LIM1 domain may be important for ILK binding. These data provide an atomic-resolution description of a key interaction in the ILK-PINCH-parvin scaffolding complex.
