Anti-general transcription factor IIA, 2, 12kDa antibodies enable researchers to detect and measure the general transcription factor IIA, 2, 12kDa antigen in biological samples. This target is a reported synonym of the GTF2A2 gene, which encodes general transcription factor IIA subunit 2. This protein is known to function in transcription by RNA polymerase II, among other biological roles. The human version of general transcription factor IIA, 2, 12kDa has a canonical amino acid length of 109 residues and a protein mass of 12.5 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include HsT18745, T18745, and TF2A2.
