    GlossaryProlactin Receptor

    protein on cell surfaces that binds to prolactin hormone

    The Prolactin Receptor (PRLR) is a protein found on the surface of certain cells that binds to the hormone prolactin. This interaction is crucial for various biological processes, including lactation, reproductive functions, and immune system regulation. In the context of hair biology, prolactin and its receptor can influence hair growth and hair cycle regulation.
