This domain is found at the C-terminus of the FTO protein which was shown to be associated with increased BMI and obesity risk in humans. The N-terminal domain of this protein is a DNA demethylase and this domain is found to associate with the N-terminal domain in the crystal structure [1]. This domain is alpha helical with three helices that form a bundle [1].	Domain
A	PF12933	FTO catalytic domain (FTO_NTD)	FTO catalytic domain	This domain is the catalytic AlkB-like domain from the FTO protein [1]. This domain catalyses a demethylase activity with a preference for 3-methylthymidine.	Domain
