Biochem/physiol Actions
Neuroendocrine hormone; belongs to the cytokine hematopoietic receptor family; induces lactation; inhibits secretion of gonadotropins; release is inhibited by dopamine.
Prolactin is a neuroendocrine hormone. The prolactin receptor is a transmembrane glycoprotein that belongs to the cytokine hematopoietic receptor family. A large number of cells and organs express the receptor, including B cells, T cells, macrophages, monocytes, and neutrophils. Prolactin signal transduction involves the JAK/STAT families and the src kinase family. Induces lactation; inhibits secretion of gonadotropins; release is inhibited by dopamine.
Physical form
Lyophilized from a solution in 10 mM phosphate and 50 mM sodium chloride, pH 8.0.
Preparation Note
It is recommended that sterile 4 mM HCl containing 1 mg/mL bovine serum albumin be added to the vial to prepare a stock solution of no less than 100 μg/mL.
Analysis Note
The biological activity is assayed by proliferation of the rat lymphoma cell line, Nb2-11.
Other Notes
Contains an N-terminal methionine not present in the natural product.

The N-terminal fragment of prolactin (16K PRL) inhibits tumor growth by impairing angiogenesis, but the underlying mechanisms are unknown. Here, we found that 16K PRL binds the fibrinolytic inhibitor plasminogen activator inhibitor-1 (PAI-1), which is known to contextually promote tumor
