RESUMO
We have previously shown that one type of high-cysteine silkmoth chorion protein (Hc-A) has evolved from the A family of chorion proteins by radical modifications of the NH2-terminal and COOH-terminal polypeptide arms: most of the arm sequences have been deleted, while short cysteine- and glycine-containing repeats have expanded into long arrays. Strikingly similar modifications of the arms have led to the evolution of a second type of high-cysteine protein (Hc-B) from the B family of chorion proteins. It appears that the parallel evolution of these high-cysteine-encoding gene families has not been entirely independent: examination of 3' untranslated regions shows evidence of information transfer between the two families.
