Background: Recently, studies on genome and transcritome of gastric cancer have suggested that gastric cancer is a heterogeneous disease caused by various genetic defects combined with environmental risk factors. In the present invention, a fusion protein expressed only in Korean gastric cancer tissues is detected by performing quantitative label-free proteome analysis.Result: A heterogeneous nuclear ribonucleoprotein A2/B1 (hnRNPA2B1)-family with sequence similarity 96 member A (FAM96A) fusion protein, which is not expressed in a normal gastric tissue, but expressed only in a gastric cancer tissue, is identified.
