Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0011546
UniProt IDQ9BYG5
Primary gene name(s)PARD6B
Synonym gene name(s)PAR6B
Protein namePartitioning defective 6 homolog beta
Protein functionAdapter protein involved in asymmetrical cell division and cell polarization processes. Probably involved in 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.
Subcellular locationCytoplasm. Cell membrane {ECO:0000250}. Cell junction, tight junction {ECO:0000250}.
