Protein

Growth hormone receptor

Gene

Ghr

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Receptor for pituitary gland growth hormone involved in regulating postnatal body growth. On ligand binding, couples to, and activates the JAK2/STAT5 pathway.
The soluble form (GHBP) acts as a reservoir of growth hormone in plasma and may be a modulator/inhibitor of GH signaling.

Post-translational modificationi

On GH binding, phosphorylated on tyrosine residues in the cytoplasmic domain by JAK2. Phosphorylation on either (or all of) Tyr-534, Tyr-566 and/or Tyr-627 is required for STAT5 activation. Phosphorylation on Tyr-333 would seem necessary for JAK2 activation.2 Publications
On ligand binding, ubiquitinated on lysine residues in the cytoplasmic domain. This ubiquitination is not sufficient for GHR internalization (By similarity).By similarity
