Background

Prolactin, also named PRL and lactotrope is a peptide hormone, encoded by the PRL gene. The structure of prolactin is similar to that of growth hormone and placental lactogen. There are mainly three different forms of prolactin in regard to size: little prolactin, big prolactin and big big prolactin. Little prolactin is the predominant form. Although often associated with human milk production, prolactin plays a wide range of other roles in both humans and other verterbrates. Rat prolactin shares 77 % ~ 90 % a.a. sequence identity with human and murine prolactin. Recombinant rat prolactin is a 22.6 kDa globular protein containing 197 amino acid residues.
