Somatotropin is a protein that in humans is encoded by the GH1 gene.The protein encoded by this gene is a member of the somatotropin/prolactin family of hormones that play an important role in growth control. The gene along with four other related genes is located at the growth hormone locus on chromosome 17 where they are interspersed in the same transcriptional orientation an arrangement thought to have evolved by a series of gene duplications.
