Box 7.14Diagrammatic representation of the structures of human GH and prolactin

Image ch7fb14.jpg

GH and prolactin contain disulfide bonds bridging two cysteine residues and they both contain between 190–200 amino acids and have regions of identical amino acid sequences. Along with human chorionic somatotrophin, this family of homologous hormones is thought to have evolved from a common ancestral gene.
