Background

Growth hormone receptor, also known as GHR is a 54 kDa transmembrane receptor and a member of the class I cytokine receptor family. Biologically active growth hormone binds to GHR, which dimerizes to activate an intracellular signal transduction pathway leading to synthesis and secretion of IGF1. In plasma, IGF1 binds to the soluble IGF1 receptor (IGF1R). At target cells, this complex activates signal-transduction via the JAK/STAT pathway, which results in the mitogenic and anabolic responses that lead to growth (1). GHR has also been shown to interact with SGTA, PTPN11 and CISH (2-4). Mutations in this gene have been associated with Laron syndrome, also known as the growth hormone insensitivity syndrome (GHIS), a disorder characterized by short stature (proportional dwarfism) (5).

Protein Details

Purity
>90% by SDS-PAGE and analyzed by silver stain.
Endotoxin Level
<0.01EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human GHR was determined by its ability to inhibit GH-induced proliferation of Nb211 rat lymphoma cells. Gout, P.W. et al., (1980) Cancer Res. 40:2433. The expected ED<sub>50</sub>= 0.4 - 2.0 ng/ml in the presence of 0.2 ng/ml of rhGH.
