Additional Info
Post Translational Modifications
The soluble form (GHBP) is produced by phorbol ester-promoted proteolytic cleavage at the cell surface (shedding) by ADAM17/TACE. Shedding is inhibited by growth hormone (GH) binding to the receptor probably due to a conformational change in GHR rendering the receptor inaccessible to ADAM17. On GH binding, phosphorylated on tyrosine residues in the cytoplasmic domain by JAK2. Ubiquitinated by the ECS(SOCS2) complex following ligand-binding and phosphorylation by JAK2, leading to its degradation by the proteasome. Regulation by the ECS(SOCS2) complex acts as a negative feedback loop of growth hormone receptor signaling. Ubiquitination is not sufficient for GHR internalization.
Function
Receptor for pituitary gland growth hormone (GH1) involved in regulating postnatal body growth. On ligand binding, couples to the JAK2/STAT5 pathway. Growth hormone-binding protein: The soluble form (GHBP) acts as a reservoir of growth hormone in plasma and may be a modulator/inhibitor of GH signaling. Isoform 2: Up-regulates the production of the soluble Growth hormone-binding protein form (GHBP) and acts as a negative inhibitor of growth hormone signaling.
