DESCRIPTION

Also known as UBR2_HUMAN, UBR2, C6orf133, KIAA0349. E3 ubiquitin-protein ligase which is a component of the N-end rule pathway (PubMed:15548684, PubMed:20835242). Recognizes and binds to proteins bearing specific N-terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation (By similarity). Plays a critical role in chromatin inactivation and chromosome-wide transcriptional silencing during meiosis via ubiquitination of histone H2A (By similarity). Binds leucine and is a negative regulator of the leucine-mTOR signaling pathway, thereby controlling cell growth (PubMed:20298436). Required for spermatogenesis, promotes, with Tex19.1, SPO11-dependent recombination foci to accumulate and drive robust homologous chromosome synapsis (By similarity). Polyubiquitinates LINE-1 retrotransposon encoded, LIRE1, which induces degradation, inhibiting LINE-1 retrotransposon mobilization (By similarity). Catalyzes ubiquitination and degradation of the N-terminal part of NLRP1 following NLRP1 activation by pathogens and other damage-associated signals: ubiquitination promotes degradation of the N-terminal part and subsequent release of the cleaved C-terminal part of NLRP1, which polymerizes and forms the NLRP1 inflammasome followed by host cell pyroptosis (By similarity). Interacts with UBE2B; promotes the UBE2B-H2A interaction and the ubiquitination of histone H2A by UBE2B and UBR2 (By similarity). Interacts with RECQL4 (PubMed:15317757, PubMed:20835242). Interacts with TEX19; does not lead to TEX19 degradation and stabilizes it (By similarity). Interacts with CASP8 (PubMed:28602583). Interacts with ATXN3 (PubMed:30455355). Interacts with UBE2O (By similarity).
