Anti-KICS2 antibodies are used in the immunodetection of the protein KICSTOR subunit 2. 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, KICS2 is known to be involved with carbohydrate metabolism and homeostasis. Synonyms for this target antigen include KICSTOR complex protein C12orf66 and UPF0536 protein C12orf66. KICS2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
