    basic FUNCTION
  • required for initiation of transcription from promoter elements such as TATA box
  • may be a component of the mechanism by which the AF-1 function of ESR1 stimulates gene transcription
  • acting as a transcription factor and modulator of apoptosis, and differentially expressed in colorectal cancer and glioblastomas
