LOXL2 and esophageal cancer: Our previous liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis of proteins that co-purify with LOXL2 and/or L2Δ13 in esophageal cancer cells identified several known metabolism-associated proteins as interacting partners that interact physically with LOXL2/L2Δ13, including glycolytic enzymes [16].
