text: # PARD6B
  
  Partitioning defective 6 homolog beta is a protein that in humans is encoded by the PARD6B gene.
  
  ## 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.
  
  ## Interactions
  
  PARD6B has been shown to interact with:
  
  * CDC42,
  * Protein kinase Mζ,
  * RAC1, and
  * RHOQ.
