|UniProt annotation for PRLR_HUMAN » Prolactin receptor|
|FUNCTION: This is a receptor for the anterior pituitary hormone prolactin (PRL). Acts as a prosurvival factor for spermatozoa by inhibiting sperm capacitation through suppression of SRC kinase activation and stimulation of AKT. Isoform 4 is unable to transduce prolactin signaling. Isoform 6 is unable to transduce prolactin signaling. SUBUNIT: Homodimer upon hormone binding. Interacts with SMARCA1. Interacts with GH1. Interacts with CSH. Interacts with NEK3 and VAV2 and this interaction is prolactin-dependent. TISSUE SPECIFICITY: Expressed in breast, placenta, kidney, liver and pancreas. DOMAIN: The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell- surface receptor binding. DOMAIN: The box 1 motif is required for JAK interaction and/or activation. DISEASE: Multiple fibroadenomas of the breast (MFAB) OMIM: A benign breast disease marked by lobuloalveolar growth with abnormally high proliferation of the epithelium, and characterized by the presence of more than 3 fibroadenomas in one breast. Fibroadenomas are adenomas containing fibrous tissue. mutations affecting the gene represented in this entry. DISEASE: Hyperprolactinemia (HPRL) OMIM: A disorder characterized by increased levels of prolactin in the blood not associated with gestation or the puerperium. HPRL may result in infertility, hypogonadism, and galactorrhea. mutations affecting the gene represented in this entry.|
