May be involved in different biological processes including transcription and apoptosis by sequestering specific proteins outside of the nucleus (By similarity). Involved in actin stress fibers formation probably through its interaction with ARHGDIA and the regulation of the Rho signaling pathway (By similarity). May thereby play a role in cell adhesion and migration, regulating for instance podocytes migration during development of the kidney (PubMed:25961457). Morpholino knockdown of the protein results in an edematous phenotype and proteinuria (PubMed:25961457). Podocyte foot process effacement and disorganization, rarefaction of slit membranes, and disorganization of the glomerular basement membrane in glomeruli which are characteritic of nephrosis are observed (PubMed:25961457).
