Serine Incorporator 2 (SERINC2)

TDE2, a gene with sequence similarity to the mouse testicular tumor-differentially-expressed (Tde1/MUSTETU) gene, was identified by serial analysis of gene expression (SAGE) in nonsmall cell lung cancers (NSCLC).TDE2 gene and determined its transcript levels in a panel of lung tumors, adjacent nonmalignant lung tissues and a variety of normal human tissues. TDE2 is a potential transmembrane protein with 11 putative transmembrane helices.TDE2 transcript levels were higher in NSCLC compared to nonmalignant samples. In nonpulmonary normal tissues, the level of TDE2 was the highest in bladder, kidney and muscle; moderate to low in stomach, liver, skin, placenta and ovary tissues; and undetectable in brain, spleen and heart.
