Salmonella typhimurium Zn2+ transporter ZntB-like subgroup; A bacterial subgroup belonging to the Escherichia coli CorA-Salmonella typhimurium ZntB_like family (EcCorA_ZntB-like) of the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes. This subgroup includes the Zn2+ transporter Salmonella typhimurium ZntB which mediates the efflux of Zn2+ (and Cd2+). Structures of the intracellular domain of Vibrio parahaemolyticus and Salmonella typhimurium ZntB form funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport through Salmonella typhimurium CorA, and Mrs2p. Natural variants such as GVN and GIN, which occur in proteins belonging to this subfamily, may be associated with the transport of different divalent cations, such as zinc and cadmium. The functional diversity of MIT transporters may also be due to minor structural differences regulating gating, substrate selection, and transport.

However its membership of this family suggests that its effect on splicing is due to altered magnesium levels in the cell.

Natural variants such as GVN and GIN, such as occur in some ZntB family proteins, may be associated with the transport of different divalent cations, such as zinc and cadmium. The functional diversity of MIT transporters may also be due to minor structural differences regulating gating, substrate selection, and transport.

uncharacterized subgroup of the Escherichia coli Mg2+ transporter CorA_like subfamily; A uncharacterized subgroup of the Escherichia coli CorA-Salmonella typhimurium ZntB_like family (EcCorA_ZntB-like) family of the MIT superfamily of essential membrane proteins involved in transporting divalent cations (uptake or efflux) across membranes. The EcCorA_ZntB-like family includes the Mg2+ transporters Escherichia coli and Salmonella typhimurium CorAs, which can also transport Co2+, and Ni2+. Structures of the intracellular domain of EcCorA_ZntB-like family members, Vibrio parahaemolyticus and Salmonella typhimurium ZntB, form funnel-shaped homopentamers, the tip of the funnel is formed from two C-terminal transmembrane (TM) helices from each monomer, and the large opening of the funnel from the N-terminal cytoplasmic domains. The GMN signature motif of the MIT superfamily occurs just after TM1, mutation within this motif is known to abolish Mg2+ transport through Salmonella typhimurium CorA. Natural variants such as GVN and GIN, such as occur in some ZntB family proteins, may be associated with the transport of different divalent cations, such as zinc and cadmium. The functional diversity of MIT transporters may also be due to minor structural differences regulating gating, substrate selection, and transport.
