这个基因编码一个巨大的卷曲螺旋蛋白，形成附着在核孔复合体（npc）内表面的核内丝。这种蛋白质直接与鼻咽癌的几种成分相互作用它是mrnas和一些蛋白质的核输出所必需的。在某些肿瘤中，该基因的5'端与几种不同的激酶基因发生致癌融合[由RefSeq提供，2008年7月]
This gene encodes a large coiled-coil protein that forms intranuclear filaments attached to the inner surface of nuclear pore complexes (NPCs). The protein directly interacts with several components of the NPC. It is required for the nuclear export of mRNAs and some proteins. Oncogenic fusions of the 5' end of this gene with several different kinase genes occur in some neoplasias. [provided by RefSeq, Jul 2008]
