SUMOylation of Blimp-1 is critical for plasma cell differentiation.
Transcriptional repressor B lymphocyte-induced maturation protein-1 (Blimp-1) is a master regulator of plasma cell differentiation. Here we show that Blimp-1 is covalently modified by SUMO1 at lysine 816, a modification mediated by SUMO E3 ligase PIAS1. Mutation of Blimp-1 lysine 816 reduces transcriptional repression--correlating with a reduced interaction with a histone deacetylase, HDAC2--an...
متن کاملDJ-1 promotes the proteasomal degradation of Fis1: implications of DJ-1 in neuronal protection.
Mutations in DJ-1/PARK7 (Parkinson protein 7) have been identified as a cause of autosomal-recessive PD (Parkinson's disease) and the antioxidant property of DJ-1 has been shown to be involved in the regulation of mitochondrial function and neuronal cell survival. In the present study, we first found that the DJ-1 transgene mitigated MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine)-induced D...
متن کاملPhosphorylation of Kif26b Promotes Its Polyubiquitination and Subsequent Proteasomal Degradation during Kidney Development
Kif26b, a member of the kinesin superfamily proteins (KIFs), is essential for kidney development. Kif26b expression is restricted to the metanephric mesenchyme, and its transcription is regulated by a zinc finger transcriptional regulator Sall1. However, the mechanism(s) by which Kif26b protein is regulated remain unknown. Here, we demonstrate phosphorylation and subsequent polyubiquitination o...
متن کاملCHIP facilitates ubiquitination of inducible nitric oxide synthase and promotes its proteasomal degradation.
Inducible nitric oxide synthase (iNOS) is responsible for nitric oxide (NO) synthesis from l-arginine in response to inflammatory mediators. It is reported that iNOS is degraded mainly by the ubiquitin-proteasome pathway in RAW264.7 cells and human embryonic kidney (HEK) 293 cells. In this study, we showed that iNOS was ubiquitinated and degraded dependent on CHIP (COOH terminus of heat shock p...
متن کاملSIAH-1 interacts with the Kaposi's sarcoma-associated herpesvirus-encoded ORF45 protein and promotes its ubiquitylation and proteasomal degradation.
Kaposi's sarcoma-associated herpesvirus (KSHV), also referred to as human herpesvirus 8, is a potentially tumorigenic virus implicated in the etiology of Kaposi's sarcoma, primary effusion lymphoma, and some forms of multicentric Castleman's disease. The open reading frame 45 (ORF45) protein, encoded by the KSHV genome, is capable of inhibiting virus-dependent interferon induction and appears t...
