The function of ZNF263 (zinc finger protein 263, ENSG00000006194) is as follows. Transcription factor that binds to the consensus sequence 5'- TCCTCCC-3' and acts as a transcriptional repressor (PubMed:32051553). Binds to the promoter region of SIX3 and recruits other proteins involved in chromatin modification and transcriptional corepression, resulting in methylation of the promoter and transcriptional repression (PubMed:32051553). Acts as a transcriptional repressor of HS3ST1 and HS3ST3A1 via binding to gene promoter regions (PubMed:32277030). .
