GREB1 N-terminal region GREB1 (gene regulated by estrogen in breast cancer 1) was first identified as an oestrogen-regulated gene expressed in breast cancer. Its exact function is not known but its expression is regulated by the coordinated binding of oestrogen-receptors to distal sites interacting with Pol II to activate gene transcription from core promoters located at a considerable distance from the greb1 gene. |
