Anti-general transcription factor IIA 2 antibodies are used in antigen-specific immunodetection in biological samples. The target general transcription factor IIA 2 is a known alias name of the protein general transcription factor IIA subunit 2, encoded by the GTF2A2 gene in humans. This 109-amino acid residue protein is known to be involved in transcription by RNA polymerase II, among other biological processes. It is localized to the nucleus of the cell.
