ZNF76 belongs to the krueppel C2H2-type zinc-finger protein family. ZNF76 is a general transcription repressor targeting TATA-binding protein (TBP), through a process regulated by sumoylation. ZNF76 interacts with TBP through both its N and C termini, and both regions are required for ZNF76 to exert its inhibitory function on p53-mediated transactivation. As a TBP-interacting transcriptional modulator, ZNF76 is also regulated by alternative splicing.
