NCIt definition : Cytoplasmic Receptors are selective binding proteins that mediate the physiologic
effects of specific bound regulatory molecules, such as hormones that cause a conformational
and functional change in the receptor molecule. Interaction of the ligand-bound receptor
with target molecules is altered, which leads to changes in cellular physiology through
modification of the activity of one or more signal transduction pathways. Steroid
receptors are cytoplasmic carriers that translocate to the nucleus upon ligand binding
and regulate the expression of specific target genes.;
