Bioinformatic membranome analysis. (A) Experimental strategy and bioinformatic algorithm to identify putative membrane proteins in FACS-purified PW1+ cardiac cells. (B) PW1+ cell putative membranome: 2,113 and 2,284 sequences were identified in cells from sham and ischemic hearts, respectively. A total of 2,040 sequences were identified under both conditions. (C) Experimental strategy to validate the newly identified candidates specifically expressed in the plasma membrane of PW1+ cardiac cells. (D) Molecular function of the 378 PW1+ cell-specific membrane proteins. ER, endoplasmic reticulum, FACS, fluorescence-activated cell sorting.
