The table summarizes the peptide sequence coverage of the different sarcoglycans identified in bands A1 to A3 (Fig. 2A) following IAP of ɛ‐sarcoglycan using esg‐4990 that detects all ɛ‐sarcoglycan isoforms. A complete list of peptides identified in these experiments can be found in Supplementary Table 1.
