Proteins, whose abundance was up- or down-regulated in rpS6^P−/− soleus.

Protein samples from soleus of wild type and rpS6P−/− mice (2 of each genotype) were subjected to ITRAQ analysis, and the fold change in mutants relative to wild type was calculated, as described in Material and Methods. Only proteins, for which the difference between the measurements for the two samples of each genotype was ≤12%, were selected for this presentation. aIn parenthesis is the number of peptides used for identification of the protein and calculation of its relative abundance. bBased on Protein Knowledgebase (http://www.uniprot.org/uniprot/).
