2.A.4.2.5
Solute carrier family 30, member 10, ZnT10.  Manganese efflux transporteer of 485 aas and 6 TMSs in a 4 + 2 TMS arrangement with two long hydrophilic regions between residues 135 and 240, and residues 300 and 485 (Nishito et al. 2016).  Homozygous mutations lead to the development of familial manganese Mn2+-induced parkinsonism; it is a cell surface-localized Mn2+ efflux transporter, and parkinsonism-causing mutations block its trafficking and efflux activity. Residues in the transmembrane and C-terminal domains together confer optimal Mn2+ transport capability (Zogzas et al. 2016). Residues involved in Mn2+ binding in the transmembrane domain have been identified, and they differ in position and nature from the Zn2+ binding site in Zn2+ transporting members of the CDF family (Zogzas and Mukhopadhyay 2018). Loss of ZnT10 expression caused by autosomal mutations in the ZnT10 gene leads to hypermanganesemia in multiple organs (Levy et al. 2019). The cellular transport of Mn2+ is coupled to a reciprocal movement of Ca2+. Replacing a single asparagine residue in ZnT10 (Asn-43) with threonine (ZnT10 N43T) converted the Mn2+/Ca2+ exchanger into an uncoupled channel permeable to both Ca2+ and Mn2+ (Levy et al. 2019). It is expressed in the CNS (Sreedharan et al. 2011).
