E3 ubiquitin-protein ligase TRIM37 (TRIM37)

E3 ubiquitin-protein ligase required to prevent centriole reduplication (PubMed:15885686, PubMed:23769972). Probably acts by ubiquitinating positive regulators of centriole reduplication (PubMed:23769972).

Mediates monoubiquitination of'Lys-119' of histone H2A (H2AK119Ub), a specific tag for epigenetic transcriptional repression: partners with some Polycomb group (PcG) multiprotein PRC2-like complex and mediates repression of target genes (PubMed:25470042). Has anti-HIV action (PubMed:24317724).
