Research Backgrounds

Function:

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 (By similarity). Involved in Schwann cell peripheral myelination (By similarity). Association with PARD6B may prevent the interaction of PARD3 with F11R/JAM1, thereby preventing tight junction assembly (By similarity). 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.

PTMs:

Acetylated. Deacetylated by SIRT2, thereby inhibiting Schwann cell peripheral myelination.

Phosphorylation at Ser-827 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-1127 phosphorylation mediates dissociation from LIMK2 (By similarity). Phosphorylation by AURKA at Ser-962 is required for the normal establishment of neuronal polarity.

Subcellular Location:

Cytoplasm. Endomembrane system. Cell junction. Cell junction>Tight junction. Cell junction>Adherens junction. Cell membrane. Cytoplasm>Cell cortex. Cytoplasm>Cytoskeleton.
Note: Localized along the cell-cell contact region. Colocalizes with PARD6A and PRKCI at epithelial tight junctions. Colocalizes with the cortical actin that overlays the meiotic spindle during metaphase I and metaphase II. Colocalized with SIRT2 in internode region of myelin sheat (By similarity). Presence of KRIT1, CDH5 and RAP1B is required for its localization to the cell junction.

Tissue Specificity:

Widely expressed.

Family&Domains:

Contains a conserved N-terminal oligomerization domain (NTD) that is involved in oligomerization and is essential for proper subapical membrane localization.

The second PDZ domain mediates interaction with membranes containing phosphoinositol lipids.

Belongs to the PAR3 family.
