Protein Information (annotations from UniProt)

Database IDHIV0000178
UniProt IDQ6VMQ6
Primary gene name(s)ATF7IP
Synonym gene name(s)MCAF, MCAF1
Protein nameActivating transcription factor 7-interacting protein 1
Protein functionRecruiter that couples transcriptional factors to general transcription apparatus and thereby modulates transcription regulation and chromatin formation. Can both act as an activator or a repressor depending on the context. Mediates MBD1-dependent transcriptional repression, probably by recruiting complexes containing SETDB1. Required to stimulate histone methyltransferase activity of SETDB1 and facilitate the conversion of dimethylated to trimethylated H3 'Lys-9', H3K9me3. The complex formed with MBD1 and SETDB1 represses transcription and couples DNA methylation and histone H3 'Lys-9' trimethylation, H3K9me3. Facilitates telomerase TERT and TERC gene expression by SP1 in cancer cells. {ECO:0000269|PubMed:12665582, ECO:0000269|PubMed:14536086, ECO:0000269|PubMed:19106100}.
