These smg-2 ELISA kits are immunodetection tools for measuring the levels of smg-2 in biological samples. smg-2 is an alias of the human UPF1 gene, which encodes the protein, UPF1 RNA helicase and ATPase. Notably, smg-2 is known to play a role in the cellular response to lipopolysaccharides and DNA repair, among other functions. The UPF1 protein is 1129 amino acid residues in length and 124.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be phosphorylated. Other names for this target antigen include HUPF1, NORF1, and RENT1. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
