Description / human Prolactin, antagonist (del 1-9) G129R protein
Prolactin, also known as mammotrophin, luterotropic hormone, and lutetropin, is a neuroendocrine hormone secreted by the pituitary gland. Its primary function is to promote and maintain lactation during pregnancy and suckling. In addition, Prolactin plays an immune-regulatory role by stimulating the activities of ornithine decarboxylase and protein kinase C, which are important for the proliferation, differentiation, and function of lymphocytes. Recombinant human prolactin antagonist del 1-9 G129R mutant has a molecular weight of approx. 22 kDa and contains 190 amino acid residues with an additional N-terminal Alanin.
