Anti-CASTOR2 antibodies are used in the immunodetection of the protein cytosolic arginine sensor for mTORC1 subunit 2. In humans, the canonical protein has a reported length of 329 amino acid residues and a mass of 36.1 kDa. Its subcellular localization is in the cytoplasm. It is widely expressed across many tissue types. A member of the GATS protein family, CASTOR2 is known to function as a negative regulator of the TORC1 signaling pathway through the GATOR complex. Synonyms for this target antigen include GATS protein-like 1, GATS-like protein 1, GATS-like protein 2, cellular arginine sensor for mTORC1 protein 2, and GATS protein like 2. CASTOR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA is a widely used application for the CASTOR2 antibodies listed below. In addition, Western Blot is also a common application.
