|W IP||H M R Mk||Endogenous||49, 75||Rabbit|
Reactivity Key: H=Human M=Mouse R=Rat Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
ASCT2 (G11) Antibody detects endogenous levels of total ASCT2 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human ASCT2 protein. Antibodies were purified by protein A and peptide affinity chromatography.
Sodium-dependent neutral amino acid transporter type 2 (ASCT2 or SLC1A5) is a neutral amino acid transporter that regulates the uptake of essential amino acids in conjunction with the SLC7A5 bilateral transporter (1,2). ASCT2 appears to be the major glutamine transporter in hepatoma cells and is thought to provide essential amino acids needed for tumor growth (3). Additional evidence suggests that ASCT2 plays a role in activating mTORC1 signaling and is required to suppress autophagy (4,5). Cell surface ASCT2 serves as a receptor for several mammalian interference retroviruses associated with cases of infectious immunodeficiency; variation in a small region of an extracellular loop (ECL2) may be responsible for species-specific differences in receptor function (6).
