  • Function
    Receptor for GRF, coupled to G proteins which activate adenylyl cyclase. Stimulates somatotroph cell growth, growth hormone gene transcription and growth hormone secretion.
  • Tissue specificity
    Pituitary gland.
  • Involvement in disease
    Defects in GHRHR are a cause of growth hormone deficiency isolated type 1B (IGHD1B) [MIM:612781]; also known as dwarfism of Sindh. IGHD1B is an autosomal recessive deficiency of GH which causes short stature. IGHD1B patients have low but detectable levels of GH.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 2 family.
  • Cellular localization
    Cell membrane.

  • Immunofluorescence analysis of HUVEC cells using ab76263 at a 1/500 dilution.
    Left image un-treated.
    Right image treated with immunizing peptide.
  • Immunofluorescence analysis of mouse pituitary cells, staining GHRHR with ab76263.

    Cells were fixed with 4% paraformaldehyde and blocked using 4% NGS in PBS with 0.3% Triton X-100 for 1 hour at room temperature. Cells were incubated with primary antibody (1/50) in 4% NGS for 18 hours at 4°C. Slides were washed three times for 15 min with PBS and then incubated in 4% NGS with an AlexaFluor®488-conjugated anti- rabbit secondary antibody (1/1000) for 1 hour at room temperature.
