This region in the nucleoside transporter proteins are responsible for determining nucleoside specificity in the human CNT1 and CNT2 proteins (e.g Swiss:O00337) [1]. In the FeoB proteins (e.g. Swiss:O25396), which are believed to be Fe2+ transporters, it includes the membrane pore region, so the function of this region is likely to be more general than just nucleoside specificity [2]. This family may represent the pore and gate, with a wide potential range of specificity. Hence its name 'Gate'.	Domain
