Anti-GCN5 antibodies enable researchers to detect and measure the GCN5 antigen in biological samples. This target is a reported synonym of the KAT2A gene, which encodes lysine acetyltransferase 2A. This protein is known to function in TNF-mediated cellular signaling pathways and chromatin remodeling, among other biological roles. The human version of GCN5 has a canonical amino acid length of 837 residues and a protein mass of 93.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. This target antigen may also be known as GCN5L2.
