Secondary Information

Protein Function involved in diverse cell adhesion-dependent physiological and pathological responses; binding partner of integrin cytoplasmic tails and was found to critically regulate fatty acids; can act as a scaffold protein to function through cellematrix interactions, cell signaling, and cytoskeletal organization; mediates many important cellular processes, including survival, proliferation, differentiation, adhesion, migration, contractility; plays some role in the activation of endothelial progenitor cells and neovascularization, and may also enhance vascular endothelial growth factor expression. Increased ILK activity may promote epithelial-to-mesenchymal transition and induce a transformed, tumorigenic phenotype
Biochemical Properties ILK has kinase activity and a preference for manganese when phosphorylating GSK-3; ILK was capable of directly phosphorylating diverse substrates including a generic substrate myelin basic protein and physiological targets including integrin ß 1 cytoplasmic tails, myosin light chain kinase LC20, cell survival kinase AKT/PKB, and glycogen synthase kinase-3 (GSK-3 ); localizes to focal adhesions, and interacts with the cytoplasmic tail of b subunits of integrins and couples them to the actin cytoskeleton
Significance in milk Forced expression of a dominant negative, kinase-dead form of ILK subtly altered mouse mammary epithelial cell morphogenesis but it did not prevent differentiative milk protein expression
