GeneCards Summary for DTX3L Gene
DTX3L (Deltex 3 Like, E3 Ubiquitin Ligase) is a Protein Coding gene. Among its related pathways are Class I MHC mediated antigen processing and presentation and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include ubiquitin-protein transferase activity and histone binding. An important paralog of this gene is DTX4.
UniProtKB/Swiss-Prot for DTX3L Gene
Ubiquitin ligase that mediates monoubiquitination of Lys-91 of histone H4 (H4K91ub1), in response to DNA damage. Protects cells exposed to DNA-damaging agents. The exact role of H4K91ub1 in DNA damage response is still unclear but it may function as a licensing signal for additional histone H4 post-translational modifications such as H4 Lys-20 methylation (H4K20me). Involved in the recruitment of 53BP1/TP53BP1 to sites of DNA damage by mediating H4K91ub1 formation. In concert with PARP9, plays a role in PARP1-dependent DNA damage repair. PARP1-dependent PARP9-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites.
