Band 4.1-like protein 4B (Epb41l4b)

Up-regulates the action of the Rho guanine nucleotide exchange factor ARHGEF18 (PubMed:22006950). Involved in the regulation of the circumferential actomyosin belt in epithelial cells (PubMed:22006950).

Promotes cellular adhesion, migration and motility in vitro and may play a role in wound healing (By similarity). May have a role in mediating cytoskeletal changes associated with steroid-induced cell differentiation (By similarity).
