Figure 6.

Electric organ proteome overlaps with mouse skeletal muscle proteome but shows tissue-specific protein expression. Mouse skeletal muscle (tibialis anterior muscle or gastrocnemius muscle) and the Torpedo electric organ were fractionated and processed under similar conditions as stated under Figure 1. Mouse skeletal muscle proteins were identified by BioWorks 3.3.1 referencing only UniProtKB/Swiss-Prot. Electric organ (EO) and skeletal muscle proteins were compared and graphed in Microsoft Excel 2007 based on the number of peptides per protein identified in each tissue. EO proteins are mapped (#peptides/protein) on the × axis and mouse skeletal muscle on the y axis. The lower two graphs represent zoomed sections for visual clarity.
