Understanding the multiple functions of Nramp1
Open accessAbstract
Nramp1 regulates macrophage activation in infectious and autoimmune diseases. Nramp2 controls anaemia. Both are divalent cation (Fe(2+), Zn(2+), and Mn(2+)) transporters; Nramp2 a symporter of H(+) and metal ions, Nramp1 a H(+)/divalent cation antiporter. This provides a model for metal ion homeostasis in macrophages. Nramp2, localised to early endosomes, delivers extracellularly acquired divalent cations into the cytosol. Nramp1, localised to late endosomes/lysosomes, delivers divalent cations from the cytosol to phagolysosomes. Here, Fe(2+) generates antimicrobial hydroxyl radicals via the Fenton reaction. Zn(2+) and Mn(2+) may also influence endosomal metalloprotease activity and phagolysosome fusion. The many cellular functions dependent on metal ions as cofactors may explain the multiple pleiotropic effects of Nramp1, and its complex roles in infectious and autoimmune disease.

“Iron homeostasis and Lnc2 formation are also linked to the activity of natural resistance associated macrophage protein 1 (NRAMP1 or SLC11A1), conferring resistance to infections with intracellular pathogens, such as Leishmania, Salmonella, or Mycobacteria (219, 220).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
