Family in the SLOG superfamily, found in several eukaryotic channels including diverse ciliate channels and the TRPM class of animal ion channels. Positioned near the N-terminus of all TRPM channels, it is predicted to play a regulatory role for the channel in potentially recognizing a universal nucleotide or nucleotide-derived ligand [1].

This domain is found in human Transient receptor potential cation channel subfamily M member 2 (TRPM2) and similar proteins. TRPM2 is a nonselective, voltage-independent cation channel that mediates Na+ and Ca2+ influx, leading to increased cytoplasmic Ca2+ levels. It plays a role in mediating behavioural and physiological responses to moderate heat, insulin secretion, dendritic cell differentiation and maturation and the the regulation of the reorganisation of the actin cytoskeleton and filopodia formation. This domain is found associated with Pfam:PF00520 and adopts an all-alpha configuration.	Domain

NUDT9 hydrolyses ADP-ribose (ADPR) to AMP and ribose 5'-phosphate. This domain, which has an alpha-beta configuration is ...	This domain is found towards the N-terminal end of human ADP-ribose pyrophosphatase, mitochondrial (NUDT9) and similar sequences. NUDT9 hydrolyses ADP-ribose (ADPR) to AMP and ribose 5'-phosphate. This domain, which has an alpha-beta configuration is often found associated to a catalytic C-terminal Nudix domain (Pfam:PF00293) [10,6].	Domain
