该基因编码的蛋白质含有一个UBX结构域，与葡萄糖转运蛋白4（GLUT4）相互作用这种蛋白质是一种系链，在没有胰岛素的情况下，它将肌肉和脂肪细胞内囊泡中的glut4隔离，并在胰岛素刺激的几分钟内将glut4重新分配到质膜上。该基因与转录因子tfe3基因的易位t（x；17）（p11；q25）导致肺泡软组织肉瘤和肾细胞癌中的aspscr1-tfe3融合蛋白。已发现多个选择性剪接的转录变体[由RefSeq提供，2011年10月]
The protein encoded by this gene contains a UBX domain and interacts with glucose transporter type 4 (GLUT4). This protein is a tether, which sequesters the GLUT4 in intracellular vesicles in muscle and fat cells in the absence of insulin, and redistributes the GLUT4 to the plasma membrane within minutes of insulin stimulation. Translocation t(X;17)(p11;q25) of this gene with transcription factor TFE3 gene results in a ASPSCR1-TFE3 fusion protein in alveolar soft part sarcoma and in renal cell carcinomas. Multiple alternatively spliced transcript variants have been found. [provided by RefSeq, Oct 2011]
