title: Ribosomal proteins of sea urchin eggs. I. Characterization of cytoplasmic ribosomal proteins.
abstract: Ribosomal proteins from the eggs of sea urchin, Pseudocentrotus depressus, were analyzed by two-dimensional polyacrylamide gel electrophoresis (PAGE) and sodium dodecyl sulfate (SDS)-PAGE. Thirty different proteins including three acidic proteins were detected in the small subunit. The large subunit was found to contain at least 43 different proteins, 42 basic and one acidic. The ribosomal proteins from the small subunit have molecular weights ranging from 11,900 to 51,700 (average molecular weight: 25,600). The molecular weights of the large subunit proteins range from 12,700 to 76,300 (average molecular weight: 28,700).
