  • FunctionReceptor for follicle-stimulating hormone. The activity of this receptor is mediated by G proteins which activate adenylate cyclase.
  • Tissue specificitySertoli cells and ovarian granulosa cells.
  • Involvement in diseaseDefects in FSHR are a cause of ovarian dysgenesis type 1 (ODG1) [MIM:233300]; also known as premature ovarian failure or gonadal dysgenesis XX type or XX gonadal dysgenesis (XXGD) or hereditary hypergonadotropic ovarian failure or hypergonadotropic ovarian dysgenesis with normal karyotype. ODG1 is an autosomal recessive disease characterized by primary amenorrhea, variable development of secondary sex characteristics, and high serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
    Defects in FSHR are a cause of ovarian hyperstimulation syndrome (OHSS) [MIM:608115]. OHSS is a disorder which occurs either spontaneously or most often as an iatrogenic complication of ovarian stimulation treatments for in vitro fertilization. The clinical manifestations vary from abdominal distention and discomfort to potentially life-threatening, massive ovarian enlargement and capillary leak with fluid sequestration. Pathologic features of this syndrome include the presence of multiple serous and hemorrhagic follicular cysts lined by luteinized cells, a condition called hyperreactio luteinalis.
  • Sequence similaritiesBelongs to the G-protein coupled receptor 1 family. FSH/LSH/TSH subfamily.
    Contains 9 LRR (leucine-rich) repeats.
    Contains 1 LRRNT domain.
  • Post-translational
    N-glycosylated; indirectly required for FSH-binding, possibly via a conformational change that allows high affinity binding of hormone.
  • Cellular localizationCell membrane.

  • ICC/IF image of ab103874 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab103874, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% formaldehyde fixed (10 min) HepG2 cells at 5µg/ml, and in 100% methanol fixed (5 min) HeLa, HepG2 and MCF7 cells at 5µg/ml.

Thank you for your reply.

Do you have access to rat or human tissue sections to run a positive control? I do agree that the localization should be in the granulosa cells, but the trouble with this is that the antibody is not validated for ham...

Thank you for your inquiry.

We haven't tested this antibody on golden hamster ovary tissue sections, so we are unsure how or if it will cross-react.

I hope this information helps. Please contact us with any other questions.
