Research Abstract

The LUBAC ubiquitin ligase activates NF-kappaB by generating linear polyubiquitin chains. Previously, we have identified HOIL-1L and HOIP as components of LUBAC. In this study, we identified SHARPIN as the other subunit of LUBAC. Cpdm mice, a spontaneous mutant mice that exhibit pleomorphic phenotypes including chronic dermatitis, lack SHARPIN. We found that destabilization of the other subunits of LUBAC and lack of SHARPIN are causative for the phenotypes of cpdm mice. We also examined the roles of LUBAC mediated linear polyubiquitination in B cells and found that LUBAC's ligase activity is necessary for B1 cell development and antibody responses to thymus-dependent and thymus-independent-II antigens.
