These ERT2 ELISA kits are immunodetection tools for measuring the levels of ERT2 in biological samples. ERT2 is an alias of the human MAPK3 gene, which encodes the protein, mitogen-activated protein kinase 3. Notably, ERT2 is known to play a role in the apoptotic pathway and Bergmann glial cell differentiation, among other functions. The MAPK3 protein is 379 amino acid residues in length and 43.1 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. This protein is known to be ubiquitinated and phosphorylated. Other names for this target antigen include ERK-1 and ERK1.
