Western blot shows lysates of U‑118‑MG human glioblastoma/astrocytoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human FTO Monoclonal Antibody (Catalog # MAB7208) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for FTO at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

FTO (FATSO; also known as Fat Mass and Obesity Associated gene) is a 58 kDa member of the AlkB family of Ferrous/2-Oxoglutarate-dependent oxidative DNA/RNA demethylases. It is found the nucleus, and apparently serves to protect single stranded RNA and DNA against methylation. Although FTO is ubiquitously expressed, it has high levels in neurons that are involved in regulating energy intake, and is often found to colocalize with Oxytocin. Evidence suggests it promotes feeding behavior. Human FTO is 505 amino acids (aa) in length. It contains one dioxygenase catalytic region (aa 32-327) and a C-terminal FTO domain (aa 329-500). There are three potential isoform variants. One shows a ten aa substitution for aa 1-455, a second contains a 35 aa substitution for aa 1-413, and a third utilizes an alternative start site at Met400. Over aa 1-178, human FTO shares 89% aa identity with mouse FTO.
