Summary: This gene is a member of the PAR6 family and encodes a protein with a PSD95/Discs-large/ZO1 (PDZ) domain, an OPR domain and a semi-Cdc42/Rac interactive binding (CRIB) domain. This cytoplasmic protein is involved in asymmetrical cell division and cell polarization processes as a member of a multi-protein complex. [provided by RefSeq, Jul 2008]

reduced expression of PKCzeta/Pard3/Pard6 contributes to non-small-cell lung cancer epithelial-mesenchymal transition, invasion, and chemoresistance.
Title: Downregulation of PKCζ/Pard3/Pard6b is responsible for lung adenocarcinoma cell EMT and invasion.
found that the polarity determinants Cdc42, Par6B, PKCzeta/iota and the structural proteins ezrin and phospho-ezrin were lost from the apical membrane and accumulated either in the cytoplasm or on the basal side of enterocytes in patients
Title: The localisation of the apical Par/Cdc42 polarity module is specifically affected in microvillus inclusion disease.
PAK4 phosphorylates Par6B at Ser143 blocking its interaction with Cdc42.
Title: Functional cross-talk between Cdc42 and two downstream targets, Par6B and PAK4.
Data conclude that Par6B and aPKC control mitotic spindle orientation in polarized epithelia and, furthermore, that aPKC coordinately regulates multiple processes to promote morphogenesis.
Title: Par6B and atypical PKC regulate mitotic spindle orientation during epithelial morphogenesis.
This study demonstrates that controlled regulation of PAK4 is required for apical junction formation in lung epithelial cells and highlights potential cross-talk between two Cdc42 targets, PAK4 and Par6B.
Title: Cdc42 regulates apical junction formation in human bronchial epithelial cells through PAK4 and Par6B.
Interaction between PAR-3 and the aPKC-PAR-6 complex is indispensable for apical domain development of epithelial cells.
Title: Interaction between PAR-3 and the aPKC-PAR-6 complex is indispensable for apical domain development of epithelial cells.
The ability of SRC family coactivators to regulate the expression of one of these genes, PARD6B/Par6, was confirmed by using cells individually depleted of SRC-1.
Title: Identification of target genes in breast cancer cells directly regulated by the SRC-3/AIB1 coactivator.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
