title: Ribosomal proteins of sea urchin eggs. II. Taxonomical differences.
abstract: Ribosomal proteins from unfertilized eggs of three sea urchin species. Pseudocentrotus depressus, Hemicentrotus pulcherrimus, and Anthocidaris crassispina, were analyzed. Species-specific differences were observed in the profiles of large subunit proteins on two-dimensional slab gels, though the number of ribosomal proteins and the molecular weights of their counterparts were the same. The small subunit proteins revealed similarities in the electrophoretic profiles and in the phosphorylation patterns among these three species.
