Anti-ASPSCR1 tether for SLC2A4, UBX domain containing antibodies are used for the immunodetection of the protein encoded by the ASPSCR1 gene. In humans, the canonical protein has a reported length of 553 amino acid residues and a mass of 60.2 kDa. Its subcellular localization is in the membrane, nucleus, ER, and cytoplasm. Alternative splicing is reported to yield 4 different isoforms for this protein. It is ubiquitously expressed across many tissue types. It is reported to be a tethering protein that sequesters GLUT4-containing vesicles in the cytoplasm in the absence of insulin. Other names for this target antigen include ASPSCR1, UBX domain containing tether for SLC2A4, UBX domain protein 9, UBX domain-containing protein 9, and tether containing UBX domain for GLUT4. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
