Thyroid Hormone Receptors. Thyroid hormones act by binding to cytosolic receptors of the steroid-thyroid hormone receptor superfamily (nuclear receptors) identified as thyroid hormone receptors (TR).

Synthesis of the male sex hormones in Leydig cells of the testis. P450SSC, 3Î²-DH, and P450c17 are the same enzymes as those needed for adrenal steroid hormone synthesis.
