|UniProt annotation for GHR_HUMAN » Growth hormone receptor|
|FUNCTION: Receptor for pituitary gland growth hormone involved in regulating postnatal body growth. On ligand binding, couples to the JAK2/STAT5 pathway (By similarity). FUNCTION: The soluble form (GHBP) acts as a reservoir of growth hormone in plasma and may be a modulator/inhibitor of GH signaling. FUNCTION: Isoform 2 up-regulates the production of GHBP and acts as a negative inhibitor of GH signaling. SUBUNIT: On growth hormone (GH) binding, forms homodimers and binds JAK2 via a box 1-containing domain. Binding to SOCS3 inhibits JAK2 activation, binding to CIS and SOCS2 inhibits STAT5 activation. Interacts with ADAM17. TISSUE SPECIFICITY: Expressed in various tissues with high expression in liver and skeletal muscle. Isoform 4 is predominantly expressed in kidney, bladder, adrenal gland and brain stem. Isoform 1 expression in placenta is predominant in chorion and decidua. Isoform 4 is highly expressed in placental villi. Isoform 2 is expressed in lung, stomach and muscle. Low levels in liver. 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. DOMAIN: The extracellular domain is the ligand-binding domain representing the growth hormone-binding protein (GHBP). DOMAIN: The ubiquitination-dependent endocytosis motif (UbE) is required for recruitment of the ubiquitin conjugation system on to the receptor and for its internalization. DISEASE: Laron syndrome (LARS) OMIM: A severe form of growth hormone insensitivity characterized by growth impairment, short stature, dysfunctional growth hormone receptor, and failure to generate insulin-like growth factor I in response to growth hormone. disease is caused by mutations affecting the gene represented in this entry. DISEASE: Growth hormone insensitivity, partial (GHIP) OMIM: A disease characterized by partial resistance to growth hormone resulting in short stature. Short stature is defined by a standing height more than 2 standard deviations below the mean (or below the 2.5 percentile) for sex and chronological age, compared with a well-nourished, healthy, genetically relevant population. caused by mutations affecting the gene represented in this entry.|
