The ribosomal proteins of drosophila melanogaster. IV. Characterization by two-dimensional gel electrophoresis of the ribosomal proteins from nine postembryonic developmental stages.


The ribosomal proteins from nine postembryonic developmental stages of Drosophila melanogaster were analyzed by two-dimensional gel electrophoresis. The ribosomal protein patterns thus obtained constitute reliable control patterns against which any potential mutant can be compared. Furthermore, the results provide increased evidence for a qualitative and quantitative change in the protein composition of the total population of ribosomes which occurs mainly during the third larval instar. Two acidic proteins were found, which may be homologous with rat liver ribosomal proteins L40/L41 and E. coli proteins L7/L12.
