KiSS1-izvedeni peptidni receptor (takođe poznat kao KISS1R, GPR54 ili Kispeptinski receptor) je G protein-spregnuti receptor[1] koji vezuje peptidni hormon kispeptin (metastin).[2][3][4] Kispeptin je kodiran genom supresora metastaze KISS1, koji je izražen u raznim endokrinim i gonadnim tkivima.[5] Aktivacija kispeptinskog receptora je vezana sa kaskadom fosfolipaze C i inozitol trisfosfata u ćelija.[6]

Funkcija

[uredi | uredi kod]

Kispeptin učestvuje u regulaciji endokrinih funkcija i početka puberteta. Aktivacija kispeptinskog receptora inicira otpuštanje gonadotropin-oslobađajućeg hormona (GnRH).[7][8] Otpuštanje samog kispeptina inhibira estradiol, a podstiče GnRH.[9] Snižavanje nivoa kispeptina sa godinama je jedan od mogućih razloga za opadanje nivoa drugih endokrinih hormona, kao što je luteinizirajući hormon.[10]
