  • Function

    Adapter protein involved in asymmetrical cell division and cell polarization processes. Probably involved in the formation of epithelial tight junctions. Association with PARD3 may prevent the interaction of PARD3 with F11R/JAM1, thereby preventing tight junction assembly. The PARD6-PARD3 complex links GTP-bound Rho small GTPases to atypical protein kinase C proteins.
  • Tissue specificity

    Expressed in pancreas, skeletal muscle, brain and heart. Weakly expressed in kidney and placenta.
  • Sequence similarities

    Belongs to the PAR6 family.
    Contains 1 OPR domain.
    Contains 1 PDZ (DHR) domain.
    Contains 1 pseudo-CRIB domain.
  • Domain

    The pseudo-CRIB domain together with the PDZ domain is required for the interaction with Rho small GTPases.
    The OPR domain mediates interactions with MAP2K5.
    The PDZ domain mediates the interaction with CRB3.
  • Cellular localization

    Cytoplasm. Cell membrane. Cell projection > ruffle. Cell junction > tight junction. Colocalizes with GTP-bound CDC42 or RAC1 at membrane ruffles and with PARD3 and PRKCI at epithelial tight junctions.

  • Anti-PAR6 antibody (ab49776) at 1 µg/ml + PARD6A partial Human Recombinant Tagged Protein at 0.2 µg

    IRDye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/10000 dilution

    Performed under reducing conditions.

    Predicted band size: 37 kDa
    Observed band size: 37 kDa

  • ICC/IF image of ab49776 stained human MCF7 cells. The cells were methanol fixed (5 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab49776, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HeLa and HEK 293 cells.
