Prolactin (PRL) is a secreted neuroendocrine pituitary hormone that acts primarily on the mammary gland to promote lactation; but has pleiotropic effects in both males and females. Non-glycosylated prolactin is produced by the pituitary and packaged in storage granules before secretion; while glycosylated prolactin is reported to be constitutively secreted; have lower biological potency; and be removed from the circulation more quickly. Prolactin is synthesized mainly by the anterior pituitary in all mammals; where secretion is under tonic inhibition by hypothalamic dopamine. In humans; prolactin is also produced peripherally. Prolactin expression is low during early human pregnancy; but increases in late pregnancy. The prolactin receptor (PRLR) is a transmembrane type I glycoprotein that belongs to the cytokine hematopoietic receptor family. prolactin molecule is thought to bind two receptor molecules. In addition to its lactogenic activity; peripherally produced prolactin plays roles in breast and prostate cancer development; regulation of reproductive function; and immunoregulation.
