Human Gene SLC11A2 (ENST00000394904.9) from GENCODE V44
  Description: Homo sapiens solute carrier family 11 member 2 (SLC11A2), transcript variant 16, mRNA. (from RefSeq NM_001379455)
RefSeq Summary (NM_001174125): This gene encodes a member of the solute carrier family 11 protein family. The product of this gene transports divalent metals and is involved in iron absorption. Mutations in this gene are associated with hypochromic microcytic anemia with iron overload. A related solute carrier family 11 protein gene is located on chromosome 2. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Apr 2010].

  ID: NRAM2_HUMAN
DESCRIPTION: RecName: Full=Natural resistance-associated macrophage protein 2; Short=NRAMP 2; AltName: Full=Divalent cation transporter 1; AltName: Full=Divalent metal transporter 1; Short=DMT-1;
FUNCTION: Important in metal transport, in particular iron. Can also transport manganese, cobalt, cadmium, nickel, vanadium and lead. Involved in apical iron uptake into duodenal enterocytes. Involved in iron transport from acidified endosomes into the cytoplasm of erythroid precursor cells. May play an important role in hepatic iron accumulation and tissue iron distribution.
BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 5.5-6.5 for Fe(2+) uptake;
SUBUNIT: Forms a complex with NDFIP1 and NEDD4L, in cortical neurons, in response to iron and colbalt exposure; this interaction leads to ubiquitination by NEDD4L and proteasome- dependent degradation. Interacts with NDFIP2.
SUBCELLULAR LOCATION: Endosome membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Ubiquitously expressed. Isoform 1 is highly expressed in brain. Isoform 2 is highly expressed in spleen, thymus and pancreas. Isoform 3 and isoform 4 are abundantly expressed in duodenum and kidney.
PTM: Ubiquitinated by WWP2 (By similarity).
DISEASE: Defects in SLC11A2 are a cause of hypochromic microcytic anemia (HCMA) [MIM:206100]. The disease is characterized by an abnormal hemoglobin content in the erythrocytes which are reduced in size. It may be hereditary or acquired. Mutations in SLC11A2 are associated with progressive liver iron overload and normal to moderately elevated serum ferritin levels.
MISCELLANEOUS: NRAMP2-mediated iron uptake is markedly stimulated by nifedipine in a concentration-dependent manner.
SIMILARITY: Belongs to the NRAMP family.
SEQUENCE CAUTION: Sequence=AAH02592.1; Type=Erroneous initiation; Sequence=BAA34374.1; Type=Erroneous gene model prediction;

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
