ZNF629 is a zinc finger protein predicted to function in transcriptional regulation. Based on limited published evidence, it localizes to the nucleoplasm and nucleus where it likely binds transcription cis-regulatory regions and regulates RNA polymerase II-dependent transcription through protein-protein interactions. Recent genomic analysis identified ZNF629 as a potential candidate gene associated with spontaneous abortion, though its specific role in this phenotype remains unclear 1.
