Anti-E2A antibodies are protein reagents that detect specific antigens. The E2A antigen is another term for the human protein transcription factor 3, encoded by the TCF3 gene. The protein is a reported transcriptional regulator involved in the initiation of neuronal differentiation and mesenchymal to epithelial transition (By similarity). Canonically, it has an amino acid length of 654 residues and a mass of 67.6 kilodaltons. Its subcellular localization is in the nucleus and it is expressed in many tissues, such as the bone marrow and heart muscle. Other alias names for E2A include AGM8, AGM8A, and AGM8B.
