Description
Description
Chorion proteins (Cp) are encoded by gene clusters on the X and 3rd chromosome that undergo selective gene application in ovarian follicle cells during oogenesis. The Cp genes encode the major structural components of the eggshell chorion. (Adapted from FBrf0046094, FBrf0053248 and FBrf0227210.)
