Functioni

Adapter protein involved in asymmetrical cell division and cell polarization processes. Seems to play a central role in the formation of epithelial tight junctions. Targets the phosphatase PTEN to cell junctions. Association with PARD6B 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. Required for establishment of neuronal polarity and normal axon formation in cultured hippocampal neurons (By similarity). Involved in Schwann cell peripheral myelination.By similarity1 Publication

Post-translational modificationi

Acetylated. Deacetylated by SIRT2, thereby inhibiting Schwann cell peripheral myelination.1 Publication
Phosphorylation at Ser-824 by PRKCZ and PRKCI occurs at the most apical tip of epithelial cell-cell contacts during the initial phase of tight junction formation and may promote dissociation of the complex with PARD6. EGF-induced Tyr-1123 phosphorylation mediates dissociation from LIMK2 (By similarity). Phosphorylation by AURKA at Ser-958 is required for the normal establishment of neuronal polarity (By similarity). Isoform 4 and isoform 5 are phosphorylated during oocyte maturation (Probable).By similarityCurated

Expressioni

Tissue specificityi

All isoforms are expressed in heart, while expression in brain is mainly limited to isoform 1, and to isoform 3 to a weaker level.

Developmental stagei

At the protein level, isoform 4 expression increases steadily throughout oocyte maturation, whereas isoform 5 expression decreases in the egg as compared to the oocyte. Isoform 1 and isoform 3 are expressed from E 9.5 to E14.5, while isoform 2 is not expressed.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
