Steroid hormones typically pass through the cell membrane and bind to intracellular receptors, often affecting gene expression in the nucleus. If nuclear pores are impermeable, steroid hormones cannot exert their effects. Peptide hormones, however, bind to cell surface receptors and do not require entry into the nucleus to be effective.
