[[https://www.uniprot.org/uniprot/ILK_HUMAN 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. [[https://www.uniprot.org/uniprot/PARVA_HUMAN PARVA_HUMAN]] Plays a role in sarcomere organization and in smooth muscle cell contraction. Required for normal development of the embryonic cardiovascular system, and for normal septation of the heart outflow tract. Plays a role in sprouting angiogenesis and is required for normal adhesion of vascular smooth muscle cells to endothelial cells during blood vessel development (By similarity). Plays a role in the reorganization of the actin cytoskeleton, formation of lamellipodia and ciliogenesis. Plays a role in the establishement of cell polarity, cell adhesion, cell spreading, and directed cell migration.<ref>PMID:11331308</ref> <ref>PMID:11134073</ref> <ref>PMID:15284246</ref> <ref>PMID:20393563</ref>

== Publication Abstract from PubMed ==
 +
Integrin-linked kinase (ILK) plays a pivotal role in connecting transmembrane receptor integrin to the actin cytoskeleton and thereby regulating diverse cell-adhesion-dependent processes. The kinase domain (KD) of ILK is indispensable for its function, but the underlying molecular basis remains enigmatic. Here we present the crystal structure of the ILK KD bound to its cytoskeletal regulator, the C-terminal calponin homology domain of alpha-parvin. While maintaining a canonical kinase fold, the ILK KD displays a striking pseudoactive site conformation. We show that rather than performing the kinase function, this conformation specifically recognizes alpha-parvin for promoting effective assembly of ILK into focal adhesions. The alpha-parvin-bound ILK KD can simultaneously engage integrin beta cytoplasmic tails. These results thus define ILK as a distinct pseudokinase that mechanically couples integrin and alpha-parvin for mediating cell adhesion. They also highlight functional diversity of the kinase fold and its "active" site in mediating many biological processes.
