IFITM3（interferon induced transmembrane protein 3），癌症关联基因，基因ID：10410，该基因编码的蛋白质是干扰素诱导的膜蛋白，有助于增强对甲型H1N1流感病毒、西尼罗河病毒和登革病毒的免疫力已经发现了两个转录变体，其中只有一个是蛋白质编码的。另一个编码N-末端截短亚型的变体已被报道，但该变体的全长性质尚未确定。[由RefSeq提供，2012年5月]The protein encoded by this gene is an interferon-induced membrane protein that helps confer immunity to influenza A H1N1 virus， West Nile virus， and dengue virus. Two transcript variants， only one of them protein-coding， have been found for this gene. Another variant encoding an N-terminally truncated isoform has been reported， but the full-length nature of this variant has not been determined. [provided by RefSeq， May 2012]。
