Deltex E3 ubiquitin ligase 3L (DTX3L)

Target
DTX3L
Molecular classification
Enzyme, E3 ubiquitin ligase, RING-type ubiquitin ligase
01

Overview

DTX3L is an E3 ubiquitin ligase that plays crucial roles in DNA damage repair, antiviral responses, and signal transduction. It uniquely can ubiquitinate both protein substrates (including histones) and single-stranded nucleic acids. The protein forms important complexes with PARP9 and is over-expressed in chemotherapy-resistant lymphomas, making it a potential therapeutic target for cancer treatment.
