Summary: Predicted to be involved in several processes, including centrosome cycle; establishment or maintenance of cell polarity; and protein-containing complex assembly. Located in several cellular components, including apical plasma membrane; bicellular tight junction; and cell cortex. Is expressed in cerebral cortex; early conceptus; lung epithelium; and renal vesicle. Orthologous to human PARD6B (par-6 family cell polarity regulator beta).

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.
