Partitioning defective 6 homolog beta is a protein that in humans is encoded by the PARD6B gene.[5][6]

Function

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.[6]

Interactions

PARD6B has been shown to interact with:

CDC42,[5][7][8]
Protein kinase Mζ,[5]
RAC1,[5] and
RHOQ.[7][8]
