Tether containing UBX domain for GLUT4 (TUG) is a protein that in humans is encoded by the ASPSCR1 gene.[3][4][5]

This gene is a candidate gene for alveolar soft part sarcoma (ASPS). It has been found that ASPSCR1 can undergo oncogenic rearrangement with transcription factor TFE3 gene, creating an aberrant gene that is a stronger transcriptional activator than TFE3 alone.[6] This fusion oncogene encodes for a chimeric transcription factor, which is responsible for the production of multiple molecules that contribute to ASPS and also to renal cell carcinomas.[7] Several alternatively spliced transcript variants of this gene have been described, but their full length nature has not been determined.[5]
