ZBTB1

Acts as a transcriptional repressor (PubMed:20797634). Represses cAMP-responsive element (CRE)-mediated transcriptional activation (PubMed:21706167). In addition, has a role in translesion DNA synthesis. Requires for UV-inducible RAD18 loading, PCNA monoubiquitination, POLH recruitment to replication factories and efficient translesion DNA synthesis (PubMed:24657165). Plays a key role in the transcriptional regulation of T lymphocyte development (By similarity).

Nucleus
Nucleus, nucleoplasm
Localized in dot-like structures in the nucleus (PubMed:21706167).
Colocalized with SMRT in nuclear bodies (PubMed:20797634).
The sumoylated form is preferentially located in the nucleoplasm outside the nuclear bodies(PubMed:20797634).

Sumoylated with SUMO2 at Lys-328 and to a lesser extent at Lys-265. Sumoylation inhibits its transcriptional repression activity and regulates its subcellular localization.
