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]
