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. Interacts with TGFB1I1 (By similarity).
