Anti-Partitioning-defective 3 Antibody

半岛bd体育手机客户端 说明

一般描述

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.
