Abstract
One type of high-Cys silkmoth chorion protein (Hc-A) 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 were deleted, while short Cys- and Gly-containing repeats have expanded into long arrays. Strikingly similar modifications of the arms have led to the evolution of a 2nd type of high-Cys protein (Hc-B) from the B family of chorion proteins. The parallel evolution of these high-Cys-encoding gene families was not entirely independent: examination of 3'' untranslated regions shows evidence of information transfer between the 2 families.This publication has 18 references indexed in Scilit:
