What is the function of this protein?
E3 ubiquitin-protein ligase which is a component of the N-end rule pathway (PubMed:14585983, PubMed:31268597, PubMed:30872531).  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 (PubMed:14585983, PubMed:31268597, PubMed:30872531).  Plays a critical role in chromatin inactivation and chromosome-wide transcriptional silencing during meiosis via ubiquitination of histone H2A (PubMed:14585983, PubMed:20080676).  Binds leucine and is a negative regulator of the leucine-mTOR signaling pathway, thereby controlling cell growth (By similarity).  Required for spermatogenesis, promotes, with Tex19. 1, SPO11-dependent recombination foci to accumulate and drive robust homologous chromosome synapsis (PubMed:28708824).  Polyubiquitinates LINE-1 retrotransposon encoded, LIRE1, which induces degradation, inhibiting LINE-1 retrotransposon mobilization (PubMed:28806172).  Catalyzes ubiquitination and degradation of the N-terminal part of Nlrp1b following Nlrp1b 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 Nlrp1b, which polymerizes and forms the Nlrp1b inflammasome followed by host cell pyroptosis (PubMed:31268597, PubMed:30872531).
