Anti-CNIL antibodies are used in antigen-specific immunodetection in biological samples. The target CNIL is a known alias name of the protein cornichon family AMPA receptor auxiliary protein 1, encoded by the CNIH1 gene in humans. This 144-amino acid residue protein is reported to be involved in selective transport and maturation of TGF-alpha family proteins. It is localized to the ER and Golgi of the cell. In terms of tissue expression, it is reported to be highly expressed in the heart, liver, skeletal muscle, pancreas, adrenal medulla and cortex, thyroid, testis, spleen, appendix, peripheral blood lymphocytes and bone marrow.
