Gonadotropin-releasing hormone (GnRH) is the key peptide in the hypothalamo-hypophysial-gonadal axis, the core of regulation of reproduction in vertebrates. In this study, an octopus peptide with structural features similar to vertebrate GnRHs was isolated from brains of Octopus vulgaris. This peptide showed luteinizing hormone-releasing activity in quail anterior pituitary cells. A cDNA encoding the precursor protein was cloned. The RT-PCR transcripts were expressed in the supraesophageal and… CONTINUE READING
