Functioni

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

Expressioni

Tissue specificityi

Expressed in normal and tumorous mammary tissues, being localized in epithelial and myoepithelial/spindle cell components and in the activated fibroblasts of desmoplastic tumor stroma. Isoform 1, isoform 2 and isoform 3 are found in both normal and tumorous mammary tissues, isoform 1 being the predominant isoform. Isoform 1, isoform 3, isoform 4 and isoform 5 are expressed in the CMT-U335 cell line.

Interactioni

Subunit structurei

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.By similarity

Domaini

The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
The box 1 motif is required for JAK interaction and/or activation.
The extracellular domain is the ligand-binding domain representing the growth hormone-binding protein (GHBP).
The ubiquitination-dependent endocytosis motif (UbE) is required for recruitment of the ubiquitin conjugation system on to the receptor and for its internalization.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
