Prolactin Receptor (PRLR) Antibody – Rabbit

This gene encodes a receptor for the anterior pituitary hormone, prolactin, and belongs to the type I cytokine receptor family. Prolactin-dependent signaling occurs as the result of ligand-induced dimerization of the prolactin receptor. Several alternatively spliced transcript variants encoding different membrane-bound and soluble isoforms have been described for this gene, which may function to modulate the endocrine and autocrine effects of prolactin in normal tissue and cancer.

PRLR: receptor for the anterior pituitary hormone prolactin and placental lactogen I and II. Interacts with Cyclophilin A, differentially regulating various signaling pathways from the PrlR. Prolactin signaling is attenuated by threonine and tyrosine phosphorylation. Two alternative splice isoforms have been identified.
