Tug (Tether containing UBX domain for GLUT4), also known as ASPL, ASPSCR1, RCC17, UBXD9, UBXN9, was first identified as a chromosomal translocation partner for TFE3 in patients with Alveolar soft part sarcoma and contains an UBX-like domain in its C-terminal region. Tug is found to tether GLUT4 in intracellular vesicles and to release GLUT4 for cell surface translocation upon insulin stimulation . Stable Tug depletion or expression of a dominant negative form stimulates GLUT4 redistribution.Ladanyi, M. et al. (2001) Oncogene 20, 48-57. Bogan, J.S. et al. (2003) Nature 425, 727-33.

Host
Rabbit
Immunogen
Peptide sequence around aa.303 ~307(P-Q-Q-E-Q) derived from Human ASPSCR1.
Involvement In Disease
A chromosomal aberration involving ASPSCR1 is found in patients with alveolar soft part sarcoma. Translocation t(X;17)(p11;q25) with TFE3 forms a ASPSCR1-TFE3 fusion protein.

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous levels of total ASPSCR1 protein.
Tethering protein that sequesters GLUT4-containing vesicles in the cytoplasm in the absence of insulin. Modulates the amount of GLUT4 that is available at the cell surface (By similarity). Enhances VCP methylation catalyzed by VCPKMT.
Tissue Specificity
Ubiquitous. Highly expressed in testis, heart, skeletal muscle and pancreas.
