THAP2, also named as THAP domain-containing protein 2, is a 228 amino acid protein, which contains one THAP-type zinc finger. Members of the THAP (thanatos-associated protein) family of proteins contain a well conserved DNA-binding domain known as the THAP-type zinc finger motif. Proteins containing the THAP-type zinc finger motif are commonly involved in transcriptional regulation, cell-cycle control, apoptosis and chromatin modification
