What is KICS2 and what cellular functions does it participate in?

KICS2 (KICSTOR subunit 2) is a protein involved in carbohydrate metabolism and homeostasis. In humans, the canonical protein has a reported length of 445 amino acid residues with a molecular mass of approximately 50.4 kDa . KICS2 is also known by the synonyms KICSTOR complex protein C12orf66 and UPF0536 protein C12orf66 .

To study KICS2 function, researchers typically employ antibody-based detection methods combined with functional metabolic assays. When designing experiments to investigate KICS2's role in metabolism, consider:
