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. Interacts with integrin-linked protein kinase 1 (ILK) via the first LIM domain, and in competition with LIMS1. Part of the heterotrimeric IPP complex composed of integrin-linked kinase (ILK), LIMS1 or LIMS2, and PARVA (By similarity). Interacts with TGFB1I1. Detected in heart, lung, kidney, liver, urinary bladder, fat, skin, skeletal muscle, uterus, large intestine and testis. Not detectable during early stages of embryogenesis. Detected at low levels at 14.5 dpc and 15.5 dpc. Highly expressed at 17.5 dpc.
