TRIM32 is an E3 ubiquitin ligase for dysbindin
Mutations in the gene encoding tripartite motif protein 32 (TRIM32) cause two seemingly diverse diseases: limb-girdle muscular dystrophy type 2H (LGMD2H) or sarcotubular myopathy (STM) and Bardet-Biedl syndrome type 11(BBS11). Although TRIM32 is involved in protein ubiquitination, its substrates and the molecular consequences of disease-causing mutations are poorly understood. In this paper, we...
متن کاملAIRE Functions As an E3 Ubiquitin Ligase
Autoimmune regulator (AIRE) gene mutation is responsible for the development of autoimmune-polyendocrinopathy-candidiasis ectodermal dystrophy, an organ-specific autoimmune disease with monogenic autosomal recessive inheritance. AIRE is predominantly expressed in medullary epithelial cells of the thymus and is considered to play important roles in the establishment of self-tolerance. AIRE conta...
متن کاملThe poxviral RING protein p28 is a ubiquitin ligase that targets ubiquitin to viral replication factories.
The poxviral RING protein p28 is a virulence factor whose molecular function is unknown. Many cellular RING-containing proteins act as ubiquitin ligases (RING-E3s) connecting selected substrate proteins to the ubiquitination machinery. Here we demonstrate that vaccinia virus p28 and its homologue in myxoma virus, M143R, can mediate the formation of polyubiquitin conjugates, while RING mutants o...
متن کاملE3 Ubiquitin Ligase Synoviolin Is Involved in Liver Fibrogenesis
BACKGROUND AND AIM Chronic hepatic damage leads to liver fibrosis, which is characterized by the accumulation of collagen-rich extracellular matrix. However, the mechanism by which E3 ubiquitin ligase is involved in collagen synthesis in liver fibrosis is incompletely understood. This study aimed to explore the involvement of the E3 ubiquitin ligase synoviolin (Syno) in liver fibrosis. METHOD...
متن کاملMechanism of Cullin3 E3 Ubiquitin Ligase Dimerization
Cullin E3 ligases are the largest family of ubiquitin ligases with diverse cellular functions. One of seven cullin proteins serves as a scaffold protein for the assembly of the multisubunit ubiquitin ligase complex. Cullin binds the RING domain protein Rbx1/Rbx2 via its C-terminus and a cullin-specific substrate adaptor protein via its N-terminus. In the Cul3 ubiquitin ligase complex, Cul3 subs...
