ILK 是一种新发现的Ser/Thr蛋白激酶。ILK能够通过与整合素β1亚单位的结合介导细胞与胞外基质的连接,以依赖于PI3K的方式激活,并通过磷酸化下游底物PKB/AKT,GSK3等胞外信号的一项下游传递,对细胞的生长,分化,迁移等进行调控。由于ILK在胞内外信号传导中起着重要的作用。并且抑制ILK的活性能够导致细胞周期的停滞和细胞程序性死亡的启动,使其成为肿瘤治疗和肿瘤药物的理想靶位点。
背景资料
Integrin-linked kinases (ILKs) couple integrins and growth factors to downstream pathways involved in cell survival, cell cycle control, cell-cell adhesion and cell motility. ILK functions as a scaffold bridging the extracellular matrix (ECM) and growth factor receptors to the actin cytoskeleton through interactions with integrin, PINCH (which links ILK to the RTKs via Nck2), CH-ILKBP and affixin.

基因名
ILK
蛋白名
Integrin-linked protein kinase
亚基
Interacts with cytoplasmic domain of beta 1 subunit of integrin. Could also interacts with beta 2, beta 3 and/or beta 5 subunit of integrin. Interacts (via ANK repeats) with LIMS1 and LIMS2. Interacts with parvins and probably TGFB1I1. Interacts (via ANK repeats) with EPHA1 (via SAM domain); stimulated by EFNA1 but independent of the kinase activity of EPHA1.
Highly expressed in heart followed by skeletal muscle, pancreas and kidney. Weakly expressed in placenta, lung and liver.
翻译后修饰
Autophosphorylated on serine residues.
相似性
Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. Contains 5 ANK repeats. Contains 1 protein kinase domain.
功能
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.
