WebApr 25, 2024 · How do hormones affect gene expression? Hormonal Control of Gene Expression The protein hormones do not enter the cell, but bind to receptors in the cell membrane and mediate gene expression through intermediate molecules. Steroids, though actually enter the cell and interact with steroid receptor proteins to control gene expression. WebFollowing hormone binding, the complex dissociates and the receptors bind to HREs in chromatin. Regulation of gene expression by hormones involves an interaction of the DNA-bound receptors with other sequence-specific transcription factors and with the general transcription factors, which is partly mediated by co-activators and co-repressors. fixio brighton
