These S1R ELISA kits are immunodetection tools for measuring the levels of S1R in biological samples. S1R is an alias of the human TMBIM4 gene, which encodes the protein, transmembrane BAX inhibitor motif containing 4. Notably, S1R is known to play a role in the apoptotic pathway, among other functions. The TMBIM4 protein is described to be 238 amino acid residues in length and 27 kilodaltons in mass. It is localized to the golgi of the cell. Other names for this target antigen include CGI-119, GAAP, and LFG4.
