WebDec 1, 2006 · The structure and evolution of the insulin gene has been previously reviewed . In this article, we focus on the sequences that lie upstream of, or flank, the transcription start site and are known to affect transcription of the gene. One major conclusion is that the rodent promoters are markedly different from the human promoter, and we urge ... WebInsulin hormone exhibits compact globular shape with a molecular weight of 6000 daltons. It is composed of two polypeptide chains held together by two interchain and two intra-chain disulfide bonds. Its secondary and tertiary structures are highly complex and essential for its metabolic potential.
