HMDB Protein ID HMDBP12750
Secondary Accession Numbers None
Name Integrin-linked protein kinase
  1. 59 kDa serine/threonine-protein kinase
  2. Beta-integrin-linked kinase
  3. ILK-1
  4. ILK-2
  5. p59ILK
Gene Name ILK
Protein Type Unknown
Biological Properties
General Function Not Available
Specific 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. Regulates cell motility by forming a complex with PARVB. Phosphorylates beta-1 and beta-3 integrin subunit on serine and threonine residues, but also AKT1 and GSK3B.
