      Background InformationPAR3 is an adapter protein involved in asymmetrical cell division and cell polarization processes. It seems to play a central role in the formation of epithelial tight junctions. Its association with PARD6B may prevent the interaction of PAR3 with F11R/JAM1, thereby preventing tight junction assembly. The PARD6-PAR3 complex links GTP bound Rho small GTPases to atypical protein kinase C proteins. PAR3 interacts with PARD6A and PARD6B. Isoform 2, but not at least isoform 3 interacts with PRKCZ. PAR3 interacts with PRCKI. PAR3 forms part of a complex with PARD6A or PARD6B, PRKCI or PRKCZ and CDC42 or RAC1. PAR3 interacts with F11R/JAM1. Antibodies against PAR3 are present in sera from patients with cutaneous T cell lymphomas.

      Entrez Gene Number
      Entrez Gene SummaryPARD proteins, which were first identified in C. elegans, are essential for asymmetric cell division and polarized growth, whereas CDC42 (MIM 116952) mediates the establishment of cell polarity. The CDC42 GTPase, which is controlled by nucleotide exchange factors (GEFs; see MIM 606057) and GTPase-activating proteins (GAPs; see MIM 604980), interacts with a large set of effector proteins that typically contain a CDC42/RAC (MIM 602048)-interactive binding (CRIB) domain.[supplied by OMIM]
