These Ewing tumor-associated antigen 1 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Ewing tumor-associated antigen 1 is an alias of the human ETAA1 gene, which encodes the protein, ETAA1 activator of ATR kinase. Notably, Ewing tumor-associated antigen 1 is known to play a role in DNA damage pathways and DNA repair, among other functions. The ETAA1 protein is described to be 926 amino acid residues in length and 103.4 kilodaltons in mass. It is localized to the nucleus of the cell. In terms of tissue specificity, it is notably expressed at high levels in the brain, liver kidney and Ewing tumor cell lines. This protein is known to be phosphorylated. Other names for this target antigen include ETAA16, ewing's tumor-associated antigen 1, and ETAA1, ATR kinase activator.
