Prolactin is a pituitary hormone which takes part in the stimulation of milk production, salt and water regulation, development, growth and reproduction. The primary step in its action is binding a specific membrane receptor (prolactin receptor) which belongs to the superfamily of class 1 cytokine receptors. PRLR varies in size (short and long forms) with tissue source and species, from ~40 kDa to 100 kDa. The PRL-R consists of at least 3 separate domains: an extracellular region with 5 cysteines which contains the prolactin binding site, a single transmembrane domain and a cytoplasmic region, the length of which appears to influence ligand binding and regulate cellular function.
