This domain is found at the C-terminal end of Activated RNA polymerase II transcriptional coactivator p15 from humans, YdbC from Lactococcus lactis, and other PC4 family members. p15 has a bipartite structure composed of an N-terminal regulatory domain and a carboxy-terminal cryptic DNA-binding domain [1-4]. Activity is controlled by protein kinases that target the regulatory domain.	Domain

This domain is found in viruses, and is about 30 amino acids in length. It is found in association with Pfam:PF02232. This domain is the C terminal of the HSV virion protein 16. This protein is a transcription promoter. The C terminal domain is the carboxyl subdomain of the acidic transcriptional activation domain. The protein binds to DNA binding proteins to carry out its function. Such proteins include TATA binding protein, CBP, TBP-binding protein, etc.	Domain
