Integrin-linked kinase (ILK): a regulator of integrin and growth-factor signalling.


PMID 10407411

Abstract

Interaction of cells with the extracellular matrix (ECM) results in the regulation of cell growth, differentiation and migration by coordinated signal transduction through integrins and growth-factor receptors. Integrins achieve signalling by interacting with intracellular effectors that couple integrins and growth-factor receptors to downstream components. One well-studied effector is focal-adhesion kinase (FAK), but recently another protein kinase, integrin-linked kinase (ILK), has been identified as a receptor-proximal effector of integrin and growth-factor signalling. ILK appears to interact with and be influenced by a number of different signalling pathways, and this provides new routes for integrin-mediated signalling. This article discusses ILK structure and function and recent genetic and biochemical evidence about the role of ILK in signal transduction.
