Anti-Transformer 2 Alpha antibodies enable researchers to detect and measure the Transformer 2 Alpha antigen in biological samples. This target is a reported synonym of the TRA2A gene, which encodes transformer 2 alpha homolog. This protein is known to function in RNA splicing, among other biological roles. The human version of Transformer 2 Alpha has a canonical amino acid length of 282 residues and a protein mass of 32.7 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells. Transformer 2 Alpha is a member of the Splicing factor SR protein family.
