Representation of the Human KISS1 gene with its exons and protein product (kisspeptin). THE Human KISS1 gene is mapped on chromosome 1q32. It consists of four exons, of which only third and fourth exons are finally translated into the 145 amino acid peptide, and it is cleaved into four forms of active kisspeptin containing 54, 14, 13, and 10 amino acids
