Anti-TATA-box binding protein associated factor, RNA polymerase I subunit A antibodies are available from several suppliers. In humans, this protein is encoded by the gene TAF1A. The protein may also be known as RNA polymerase I-specific TBP-associated factor 48 kDa, TAFI48, SL1, RAFI48, and MGC:17061. The expected protein mass is 52.7 kDa, but there are 2 reported isoforms. Variants of this antigen may also be found in other species, including canine, porcine, monkey, mouse and rat.
