Type 2 usually onsets in adulthood. It stimulates the mammary glands to produce milk (lactation): increased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands and prepare for milk production, which normally starts when levels of progesterone fall by the end of pregnancy and a suckling stimulus is present. Prolactin is a part of the cocktail of hormones in pregnancy. [60][62] It was determined that this preparation behaved anomalously in certain immunoassays and was not suitable as an IS.

It binds to corticotroph receptors in anterior pituitary to stimulate the release of ACTH & Beta-endorphin. Preproopiomelanocortin (POMC) is a large polypeptide with a MW of 31,000 (265 aa). [75] The D2 receptor is involved in the regulation of prolactin secretion, and agonists of the receptor such as bromocriptine and cabergoline decrease prolactin levels while antagonists of the receptor such as domperidone, metoclopramide, haloperidol, risperidone, and sulpiride increase prolactin levels. Several established clonal strains of rat pituitary cells which produce growth hormone in culture have been shown to secrete a second protein hormone, prolactin.
