background:
Effector of integrin and growth factor signaling, coupling surface receptors to downstream signaling molecules involved in the regulation of cell survival, cell proliferation and cell differentiation. 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.
Function:
Adapter protein in a cytoplasmic complex linking beta-integrins to the actin cytoskeleton, bridges the complex to cell surface receptor tyrosine kinases and growth factor receptors. Involved in the regulation of cell survival, cell proliferation and cell differentiation.
Subunit:
Interacts (via LIM zinc-binding 5) with TGFB1I1 (By similarity). Interacts with integrin-linked protein kinase 1 (ILK) via the first LIM domain, and in competition with LIMS2. Part of the heterotrimeric IPP complex composed of integrin-linked kinase (ILK), LIMS1 or LIMS2, and PARVA. Interacts with SH3/SH2 adapter NCK2, thereby linking the complex to cell surface receptors.
Subcellular Location:
Cell junction, focal adhesion. Cell membrane; Peripheral membrane protein; Cytoplasmic side.
Tissue Specificity:
Expressed in most tissues except in the brain.
Similarity:
Contains 5 LIM zinc-binding domains.
