Which is not a function of KISSPEPTINE 4 in fish?

Regulating dopamine secretion Correct Nutritional intervention Metabolic activity Response to photoperiodicity

Kisspeptin System in Teleosts:
Kisspeptin (Kiss1 and Kiss2) acting through G-protein coupled receptors (Gpr54 / Kiss1r, Kiss2r):
Integrates photoperiodic cues and nutritional/metabolic state with the reproductive axis.
Directly stimulates GnRH (Gonadotropin-Releasing Hormone) neurons in the preoptic area to induce FSH and LH release.
In teleost reproduction, dopamine acts as a strong gonadotropin release-inhibiting factor (GRIF), functioning independently of kisspeptin stimulation.
nalysis:
(Regulating dopamine secretion): Correct (not a primary direct role of kisspeptin).

Correct option: (1) Regulating dopamine secretion
