Proteomic analysis of left ventricles containing the obscurin R4344Q mutation linked to hypertrophic cardiomyopathy and myocardia containing obscurin lacking Immunoglobulin domains 58/59 (Ig58/59)

Cardiac lysates prepared from left ventricles of 1-year-old female wild-type mice, mice carrying the obscurin R4344Q mutation, and mice carrying obscurin lacking the Ig58/59 domains (ΔIg58/59) were subjected to isobaric tandem-mass tagging, liquid chromatography, and mass spectrometry.
