Partitioning defective 3 homolog

UniProtKB accession:  Q9Z340

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Adapter protein involved in asymmetrical cell division and cell polarization processes (PubMed:18550519). Seems to play a central role in the formation of epithelial tight junctions (By similarity). Association with PARD6B may prevent the interaction of PARD3 with F11R/JAM1, thereby preventing tight junction assembly (By similarity). The PARD6-PARD3 complex links GTP-bound Rho small GTPases to atypical protein kinase C proteins (By similarity). Required for establishment of neuronal polarity and normal axon formation in cultured hippocampal neurons (By similarity). Involved in Schwann cell peripheral myelination (PubMed:21949390). Targets the phosphatase PTEN to cell junctions (PubMed:18082612).
