Adapter protein involved in asymmetrical cell division and cell polarization processes. May play a role in the formation of epithelial tight junctions. The PARD6-PARD3 complex links GTP-bound Rho small GTPases to atypical protein kinase C proteins (By similarity).
Subcellular locations: Cytoplasm, Cell membrane, Cell junction, Tight junction
Widely expressed, with a higher expression in fetal and adult kidney.
