Zinc Finger Protein 618 Regulates the Function of UHRF2 (Ubiquitin-like with PHD and Ring Finger Domains 2) as a Specific 5-Hydroxymethylcytosine Reader.

ABSTRACT: 5-Hydroxymethylcytosine (5hmC) is an epigenetic modification that is generated by ten-eleven translocation (TET) protein-mediated oxidation of 5-methylcytosine (5mC). 5hmC is associated with transcription regulation and is decreased in many cancers including melanoma. Accumulating evidence has suggested that 5hmC is functionally distinct from 5mC. Ubiquitin-like with PHD and ring finger domains 2 (UHRF2) is the first known specific 5hmC reader that has higher affinity to 5hmC than 5mC, suggesting that UHRF2 might mediate 5hmC's function. Structural analysis has revealed the molecular mechanism of UHRF2-5hmC binding in vitro, but it is not clear how UHRF2 recognizes 5hmC in vivo In this study, we have identified zinc figure protein 618 (ZNF618) as a novel binding partner of UHRF2.
