 1-42 3.15e-19

Insulin/insulin-like growth factor/relaxin family; insulin family of proteins. Members include a number of active peptides which are evolutionary related including insulin, relaxin, prorelaxin, insulin-like growth factors I and II, mammalian Leydig cell-specific insulin-like peptide (gene INSL3), early placenta insulin-like peptide (ELIP; gene INSL4), insect prothoracicotropic hormone (bombyxin), locust insulin-related peptide (LIRP), molluscan insulin-related peptides 1 to 5 (MIP), and C. elegans insulin-like peptides. Typically, the active forms of these peptide hormones are composed of two chains (A and B) linked by two disulfide bonds; the arrangement of four cysteines is conserved in the "A" chain: Cys1 is linked by a disulfide bond to Cys3, Cys2 and Cys4 are linked by interchain disulfide bonds to cysteines in the "B" chain. This alignment contains both chains, plus the intervening linker region, arranged as found in the propeptide form. Propeptides are cleaved to yield two separate chains linked covalently by the two disulfide bonds.

 1-42 3.15e-19

IlGF, insulin_like growth factors; specific to vertebrates. Members include a number of peptides including insulin-like growth factors I and II, which play a variety of roles in controlling processes such as growth, differentiation, and reproduction. On a cellular level they affect cell cycle, apoptosis, cell migration, proliferation, and differentiation. Typically, the active forms of these peptide hormones are single chains cross-linked by three disulfide bonds.
