Binds DNA and activates transcription of CYP11A1. Interaction with CREBBP and EP300 results in a synergistic transcriptional activation of CYP11A1. Interacts with CREBBP and EP300 (PubMed:11349124). Interacts with DNTTIP1 (PubMed:16371131, PubMed:21573134). Interacts with DNTT (PubMed:16371131). Highest expression was seen in thymus, testis and adrenal cortex, expressed also in the adrenal medulla, thyroid, and stomach. Highly expressed in steroidogenic JEG-3 and MCF-7 cells, low expression was seen in non-steroidogenic Hep-G2 and HEK293 cells.
