These Atp6i ELISA kits are immunodetection tools for measuring the levels of Atp6i in biological samples. Atp6i is an alias of the human TCIRG1 gene, which encodes the protein, T cell immune regulator 1, ATPase H+ transporting V0 subunit a3. Notably, Atp6i is known to play a role in the apoptotic pathway and B cell differentiation, among other functions. The TCIRG1 protein is 830 amino acid residues in length and 93 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane of the cell. Other names for this target antigen include ATP6N1C and ATP6V0A3.
