Structure of the dmPar3 PDZ1 domain in complex with the dmPar6 PBMStructure of the dmPar3 PDZ1 domain in complex with the dmPar6 PBM
Structural highlights
FunctionPublication Abstract from PubMedPolarity is a fundamental property of most cell types. The Par protein complex is a major driving force in generating asymmetrically localized protein networks and consists of atypical protein kinase C (aPKC), Par3, and Par6. Dysfunction of this complex causes developmental abnormalities and diseases such as cancer. We identified a PDZ domain-binding motif in Par6 that was essential for its interaction with Par3 in vitro and for Par3-mediated membrane localization of Par6 in cultured cells. In fly embryos, we observed that the PDZ domain-binding motif was functionally redundant with the PDZ domain in targeting Par6 to the cortex of epithelial cells. Our structural analyses by x-ray crystallography and NMR spectroscopy showed that both the PDZ1 and PDZ3 domains but not the PDZ2 domain in Par3 engaged in a canonical interaction with the PDZ domain-binding motif in Par6. Par3 thus has the potential to recruit two Par6 proteins simultaneously, which may facilitate the assembly of polarity protein networks through multivalent PDZ domain interactions. Structural basis for the interaction between the cell polarity proteins Par3 and Par6.,Renschler FA, Bruekner SR, Salomon PL, Mukherjee A, Kullmann L, Schutz-Stoffregen MC, Henzler C, Pawson T, Krahn MP, Wiesner S Sci Signal. 2018 Feb 13;11(517). pii: 11/517/eaam9899. doi:, 10.1126/scisignal.aam9899.
