The adenovirus E1A protein both activates and represses gene expression to promote cellular proliferation and inhibit differentiation. The protein encoded by this gene antagonizes transcriptional activation and cellular transformation by E1A. Cellular Repressor Of E1A Stimulated Genes 1 shares limited sequence similarity with E1A and binds both the general transcription factor TBP and the tumor suppressor pRb in vitro. CREG1 may contribute to the transcriptional control of cell growth and differentiation. CREG1 (Cellular Repressor Of E1A Stimulated Genes 1) is a Protein Coding gene. Among its related pathways are Innate Immune System and Senescence and Autophagy in Cancer.
