Anti-CNIH antibodies enable researchers to detect and measure the CNIH antigen in biological samples. This target is a reported synonym of the CNIH1 gene, which encodes cornichon family AMPA receptor auxiliary protein 1. This protein is known to function in immune response pathways and signal transduction pathways, among other biological roles. The human version of CNIH has a canonical amino acid length of 144 residues and a protein mass of 16.7 kilodaltons. It is reported to be localized in the ER and Golgi of cells and widely expressed in many tissue types. CNIH is a member of the Cornichon protein family.
