Proteins identified by mass spectrometry from minispryn (Fig. 3a) and myospryn (Supplementary Fig. S4) immunoaffinity purification from cardiac muscle. For clarity, in this study we have only focussed on the three most significant matches from each experiment. Note that stretch-responsive fibronectin protein type 3 [Mus musculus]/gi45774102 is the alternative name for Cmya5/myospryn and fibronectin type III and SPRY domain-containing protein 2 [Mus musculus]/gi116063550 is Fsd2/minispryn.
