37-236aa, Full Length of Mature Protein. MW: 26,909 Da. Purity >85% (SDS-PAGE). This protein is a member of the somatotropinprolactin family of hormones and plays an important role in growth control. The gene is located at the growth hormone locus on chromosome 17 along with four other related genes in the same transcriptional orientation; an arrangement which is thought to have evolved by a series of gene duplications. Although the five genes share a remarkably high degree of sequence ident
