Amino-terminal amino Acid sequence of the silkworm prothoracicotropic hormone: homology with insulin

H Nagasawa et al. Science. .

Abstract

Three molecular forms of prothoracicotropic hormone were isolated from the head of the adult silkworm, Bombyx mori, and the amino acid sequence of 19 amino acid residues in the amino terminus of these prothoracicotropic hormones was determined. These residues exhibit significant homology with insulin and insulin-like growth factors.
