Anti-KICSTOR subunit 2 antibodies are used for the immunodetection of the protein encoded by the KICS2 gene. In humans, the canonical protein has a reported length of 445 amino acid residues and a mass of 50.4 kDa. Its subcellular localization is in the lysosomes. A member of the KICS2 protein family, it is known to be involved with carbohydrate metabolism and homeostasis. Other names for this target antigen include KICSTOR complex protein C12orf66 and UPF0536 protein C12orf66. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
