 The exact nature of the expression of kisspeptins in human adrenal glands unfortunately has not been fully clarified yet and remains a large topic of research among many scientists.Kisspeptin is a product of the KISS1 gene which is cleaved from an initial 145 amino acid peptide to a 54 amino acid long protein.This gene is located on the long arm of chromosome 1 (1q32) and has four exons of which the 5' and 3' exons only partly undergo translation.
