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
