Comparative biochemical analysis of the major yolk protein in the sea urchin egg and coelomic fluid.

The major yolk protein (MYP) is localized to the egg and coelomic fluid of the adult sea urchin. While the egg-localized MYP has been extensively studied, much less is known about the coelomic fluid-localized protein. Therefore, we have conducted a comparative biochemical analysis of these proteins.
