Description

General description

PAR3 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.

Analysis Note

Control
Positive Antigen Control: Catalog #12-305, 3T3/A31 lysate. Add 2.5 μL of 2-mercapto-ethanol/100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for minigels.

Evaluated by western blot on RIPA lysates from 3T3/A31, A431, and HeLa cells.

Western Blot Analysis:
0.5-2 µg/mL of this antibody detected PAR-3 isoforms in RIPA lysates from 3T3/A31, A431, and HeLa cells.
