Crystal structure of human NLRP12 PYD domain and implication in homotypic interaction.


ABSTRACT: NLRP12 is a NOD-like receptor that plays multiple roles in both inflammation and tumorigenesis. Despite the importance, little is known about its mechanism of action at the molecular level. Here, we report the crystal structure of NLRP12 PYD domain at 1.70 Å fused with an maltose-binding protein (MBP) tag. Interestingly, the PYD domain forms a dimeric configuration through a disulfide bond in the crystal. The possible biological significance is discussed in the context of ROS induced NF-?B activation.
