Kisspeptin peptides acting through GPR54 are the essential gatekeepers of puberty onset and adult reproductive function, controlling GnRH release — mutations cause both absent puberty and infertility.
Key findingKisspeptins activate GPR54 receptor to control GnRH neuron firing, serving as the essential gatekeeper for puberty onset and adult fertility — GPR54 m
What the researchers found
Kisspeptins activate GPR54 receptor to control GnRH neuron firing, serving as the essential gatekeeper for puberty onset and adult fertility — GPR54 mutations cause both absent puberty (hypogonadotropic hypogonadism) and infertility, establishing kisspeptin as the master reproductive switch.
Why it matters
Relevant for neuropeptides, fertility, receptor-signaling.
