it appears to be related to the beta-msh species of mammalian species but has only the sequence -his-phe-arg-trp- in common with the heptapeptide core -met-glu-his-phe-arg-trp-gly- which is characteristic not only of the msh peptides but also of the adrenocorticotrophins and lipotrophins studied so far .
