Listed are ELISA Kits for the detection of S863-3, an alias name of chromosome 1 open reading frame 43. The human protein, encoded by the gene C1orf43, is 253 amino acid residues long and has a mass of 28,779 daltons. However, there are up to 5 reported isoforms. This protein is reported to have a membrane cellular localization. This target may also be known as: uncharacterized protein C1orf43, HCV NS5A-transactivated protein 4, hepatitis C virus NS5A-transactivated protein 4, HSPC012, NICE3, NS5ATP4, and S863-3.
