Structurally, its extracellular region consists of two fibronectin type III domains and a WSXWS motif, while the stem domain mediates ligand-induced receptor dimerization; the intracellular tail contains Box1\/Box2 motifs that recruit JAK2 upon activation. Prolactin binding triggers conformational rearrangement, initiating the JAK2-STAT5, MAPK, and PI3K signaling pathways to govern mammary gland development, lactation initiation and maintenance, systemic metabolic homeostasis, and reproductive endocrine function. PRLR signaling carries significant clinical implications in oncology and endocrinology: prospective epidemiological studies demonstrate that elevated plasma prolactin concentrations are associated with increased risk of postmenopausal breast cancer, particularly hormone receptor-positive subtypes; conversely, acidosis within the tumor microenvironment selectively abrogates PRLR-mediated STAT5 phosphorylation, thereby disrupting the hormone's anti-invasive effects and facilitating malignant progression. Germline loss-of-function mutations in PRLR, exemplified by the His188Arg variant, result in familial hyperprolactinemia characterized by oligomenorrhea and infertility due to impaired JAK2-STAT5 signaling. Additionally, the PRLR short isoform functions as a tumor suppressor in pancreatic ductal adenocarcinoma by engaging the NEK9-Hippo axis to downregulate pentose phosphate pathway enzymes and restrain nucleotide biosynthesis. These multifaceted biological roles have positioned PRLR as an attractive therapeutic target, with clinical-stage interventions including the monoclonal antibody antagonist LFA102 and the antibody-drug conjugate ABBV-176 being evaluated in solid tumor trials.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"UA BIOSCIENCE","offers":[{"title":"25μg","offer_id":43095682121803,"sku":"UA016099-25μg","price":430.0,"currency_code":"USD","in_stock":true},{"title":"100μg","offer_id":43095682154571,"sku":"UA016099-100μg","price":850.0,"currency_code":"USD","in_stock":true},{"title":"500μg","offer_id":43095682187339,"sku":"UA016099-500μg","price":2240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/3b62fbe6732b4f2ab3bf68db15b1ea31.png?v=1788220852","url":"https:\/\/www.antbioinc.com\/products\/biotinylated-prolactin-rprlr-hisavi-tag-protein-human-ua016099","provider":"AntBio","version":"1.0","type":"link"}
