Summary
PARD6A (par-6 family cell polarity regulator alpha, HGNC:15943) is a protein-coding gene on chromosome 16q22.1, encoding Partitioning defective 6 homolog alpha (Q9NPB6). Adapter protein involved in asymmetrical cell division and cell polarization processes.
This gene is a member of the PAR6 family and encodes a protein with a PSD95/Discs-large/ZO1 (PDZ) domain and a semi-Cdc42/Rac interactive binding (CRIB) domain. This cell membrane protein is involved in asymmetrical cell division and cell polarization processes as a member of a multi-protein complex. The protein also has a role in the epithelial-to-mesenchymal transition (EMT) that characterizes the invasive phenotype associated with metastatic carcinomas. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

UniProt curated annotations — full annotation on UniProt →
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. Regulates centrosome organization and function. Essential for the centrosomal recruitment of key proteins that control centrosomal microtubule organization.
Subunit / interactions. Interacts with MAP2K5. Interacts with PARD3. Interacts with GTP-bound forms of CDC42, RHOQ/TC10 and RAC1. Interacts with the N-terminal part of PRKCI and PRKCZ. Part of a complex with PARD3, CDC42 or RAC1 and PRKCI or PRKCZ. Part of a complex with LLGL1 and PRKCI. Interacts with human T-cell leukemia virus type I TAX protein. Interacts with PALS1 and CRB3. Interacts with TGFBR1; involved in TGF-beta induced epithelial to mesenchymal transition. Interacts with ECT2 (‘Thr-359’ phosphorylated form) and PRKCI. Interacts with DCTN1 and PCM1.
Subcellular location. Cytoplasm. Cell membrane. Cell projection. Ruffle. Cell junction. Tight junction. Cytoskeleton. Microtubule organizing center. Centrosome. Centriolar satellite.
Tissue specificity. Expressed in pancreas, skeletal muscle, brain and heart. Weakly expressed in kidney and placenta.
Post-translational modifications. Phosphorylated by the TGF-beta receptor. Ubiquitinated by the SCF(FBXO31) complex, leading to its proteasomal degradation.
Domain organisation. The pseudo-CRIB domain together with the PDZ domain is required for the interaction with Rho small GTPases. The PB1 domain mediates interactions with MAP2K5. The PDZ domain mediates the interaction with CRB3.
Similarity. Belongs to the PAR6 family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 43 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
GO biological processes:
| GO term | Partners | Fold | FDR |
|---|---|---|---|
| establishment or maintenance of epithelial cell apical/basal polarity | 6 | 89.4× | 2e-08 |
| Wnt signaling pathway, planar cell polarity pathway | 5 | 58.4× | 5e-06 |
| small GTPase-mediated signal transduction | 5 | 23.5× | 3e-04 |
