Abstract:
We have combined high-resolution two-dimensional (2-D) gel electrophoresis with mass spectrometry to identifying proteins represented in a 2-D gel database of Drosophila melanogaster ribosomes. First, we purified ribosomes from third instar Drosophila larvae and constructed a high-resolution 2-D gel database containing 58 Coomassie blue stained polypeptides. Next, we carried out preparative 2-D PAGE to isolate some of the polypeptides and characterize them by MALDI-TOF. Using this strategy we identified 52 ribosomal spots in the database, and in each case confirmed their identity by MALDI-TOF/TOF. The database can be used to analyze Minute mutants of Drosophila.

Ribosome Structure and Assembly
Ribosomes are composed of ribosomal RNA (rRNA) and proteins. In eukaryotes, rRNA is transcribed from genes in the nucleolus—a part of the nucleus that specializes in ribosome production. Within...
Protein Modifications in the RER
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal sequences.
Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
