Selected proteins identified from microsomal and plasma membranes. A, Proteins identified from microsomal membrane are mapped to the apob interactome in the human protein reference database (www.hprd.org). Twelve of 17 proteins apob-interacting proteins in human protein reference database (71%) were identified from the microsomal membrane fraction. The proteins identified by membrane proteomic reactor are shown in blue color; and the proteins identified by in-gel digestion are shown in red color. B, Receptors identified from plasma membrane.
