Molecular Weight The recombinant mouse PRLR/Fc chimera is a disulfide-linked homodimer. The reduced monomer consists of 457 amino acids and has a calculated molecular mass of 52.5 kDa. As a result of glycosylation, the apparent molecular mass of the mouse PRLR/Fc monomer is approximately 65-70 kDa in SDS-PAGE under reducing conditions.

Background Prolactin receptor (PRLR) is a single-pass transmembrane receptor belonging to the type â…  cytokine receptor superfamily, and contains two fibronectin type-â…¢ domains. All class 1 ligands activate their respective receptors by clustering mechanisms. Ligand binding results in the transmembrane PRLR dimerization, followed by phosphorylation and activation of the molecules invloved in the signaling pathways, such as Jak-STAT, Ras/Raf/MAPK. The PRLR contains no intrinsic tyrosine kinase cytoplasmic domain but associates with a cytoplasmic tyrosine kinase, JAK2. PRLR mainly serves as the receptor for the pituitary hormone prolactin (PRL), a secreted hormone that affects reproduction and homeostasis in vertebrates. PRLR can be regulated by an interplay of two different mechanisms, PRL or ovarian steroid hormones independently or in combination in a tissue-specific manner. The role of the hormone prolactin (PRL) in the pathogenesis of breast cancer is mediated by its cognate receptor (PRLR). Ubiquitin-dependent degradation of the PRLR that negatively regulates PRL signaling is triggered by PRL-mediated phosphorylation of PRLR on Ser349 followed by the recruitment of the beta-transducin repeats-containing protein (beta-TrCP) ubiquitin-protein isopeptide ligase. which altered PRLR stability may directly influence the pathogenesis of breast cancer.
