ILK (Q13418) - Overview - Molecular Target Synopsis


ILK, Integrin-linked protein kinase
Enzyme Classification
UniProt Q13418

Also Known as ILK_HUMAN, ILK, ILK1, ILK2

Receptor-proximal protein kinase regulating integrin-mediated signal transduction (PubMed:8538749, PubMed:9736715). 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 (PubMed:8538749, PubMed:9736715). Interacts with FERMT2 (By similarity). Interacts with the cytoplasmic domain of ITGB1. Could also interact with integrin ITGB2, ITGB3 and/or ITGB5. Interacts (via ANK repeats) with LIMS1 and LIMS2. Interacts with PARVA and PARVB; these compete for the same binding site. Interacts probably also with TGFB1I1. Interacts (via ANK repeats) with EPHA1 (via SAM domain); stimulated by EFNA1 but independent of the kinase activity of EPHA1. Interacts with LIMD2; leading to activate the protein kinase activity (PubMed:24590809).
