Identified proteins from LIS fraction of vastus lateralis muscle of mature and old women (Supplemental Table 1) analyzed with the PANTHER bioinformatics tool (http://www.pantherdb.org) using the Gene Ontology categories “Molecular function,” “Biological Process,” and “Cellular Component.” The molecular functions “Catalytic activity” and “Binding” are detailed. For each category, the number of identified proteins and their percentage of the total number of proteins in the pie chart are indicated for each Gene Ontology term.
