Folikulostimulišući hormonski receptor ili FSH-receptor (FSHR) je transmembranski receptor koji interaguje sa Folikulostimulišućim hormonom (FSH). On je G protein-spregnuti receptor (GPCR). Njegova aktivacija je neophodna za FSH hormonsko funkcionisanje. FSHR receptori su nađeni u jajnicima, testisima, i uterusu.

FSHR gen

FSHR gen se nalazi na hromozomu 2 p21 kod čoveka. FSHR genska sekvenca se sastoji od oko 2,080 nukleotida.^[1]

Struktura receptora

Struktura G protein-spregnutog receptora kao što je FSHR sa sedam transmembranskih α-heliksa

FSHR se sastoji od 695 aminokiselina, i ima molekulsku masu od oko 76 kDa.^[1] Poput drugih GPCR receptora, FSH-receptor poseduje sedam domena (transmembranskih heliksa), svaki od kojih premoštava membranu.

Ekstracelularni domen receptora je glikoziliran.
Transmembranski domen sadrži dva visoko očuvana cisteinska ostatka koji formiraju disulfidnu vezs čime se stabilizuje struktura receptora. Visoko konzervirani Asp-Arg-Tyr triplet je prisutan i verovatno učestvuje u prenosu signala.
C-terminalni domen je intraćelijski i kratak. On bogat u ostacima serina i treonina koji služe kao moguća mesta za fosforilaciju.
