DMT1 [SEP] chromosome
for direct absorption of metals into the brain. DMT1 expression in the brain may increase with age, increasing susceptibility to metal induced pathologies. DMT1 expression is found to be increased in the substantia nigra of Parkinson's patients and in the ventral mesencephalon of animal models intoxicated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) - a neurotoxin widely used experimentally to produce Parkinsonian symptoms.
The DMT1 encoding gene SLC11A2 is located on the long arm of chromosome 12 (12q13) close to susceptibility regions for Alzheimer's disease and restless legs syndrome. The C allele
Natural resistance-associated macrophage protein 2
Natural resistance-associated macrophage protein 2 (NRAMP 2), also known as divalent metal transporter 1 (DMT1) and divalent cation transporter 1 (DCT1), is a protein that in humans is encoded by the "SLC11A2" (solute carrier family 11, member 2) gene. DMT1 represents a large family of orthologous metal ion transporter proteins that are highly conserved from bacteria to humans.
As its name suggests, DMT1 binds a variety of divalent metals including cadmium (Cd
