These p126 ELISA kits are immunodetection tools for measuring the levels of p126 in biological samples. p126 is an alias of the human DENND2B gene, which encodes the protein, DENN domain containing 2B. Notably, p126 is known to play a role in the regulation of the ERK1 and ERK2 signaling cascade, among other functions. The DENND2B protein is 1137 amino acid residues in length and 126.5 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cell membrane, cytoplasmic vesicles, and cytoplasm of the cell. In terms of tissue specificity, it is reported to be widely expressed with the exception of peripheral blood lymphocytes. This protein is known to be phosphorylated. Other names for this target antigen include HTS1 and ST5. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
