Polyclonal Rabbit Serum E B
Natural resistance to infection with unrelated intracellular parasite such as Mycobacteria, Salmonella and Leishmania is controlled by a single gene that encodes a macrophage-specific membrane protein designated as Natural Resistance-Associated Macrophage Protein (Nramp1). Recently a second member of NRAMP family, termed NRAMP2/DMT/DCT1 (Divalent Metal ion Transporter 1 or Divalent Cation Transporter 1), has been identified (human, rat and mouse 568aa, ~65% identity with NRAMP1). Unlike NRAMP1, NRAMP2 expression is more ubiquitous and has been detected in most tissues. It is dramatically up-regulated by iron starvation in the intestine. NRAMP2 (slc11a2) gene produces two alternatively spliced transcripts generated by alternative use of two 3' exons encoding distinct C-termini of the protein as well as distinct 3' untranslated regions (UTRs). Interestingly, one Nramp2 mRNA contains an iron-responsive element (IRE) in its 3'UTR. The IRE is an RNA secondary structure present in the 5'- or the 3'- UTR of animal mRNAs encoding proteins involved in iron metabolism. The second Nramp2 splice isoform (without-IRE, isoform II) encodes a protein in which the C-terminal 18-aa of the IRE form (with IRE, isoform I) are replaced by a novel 25-aa segment and codes for a distinct 3' UTR lacking the IRE. The two isoforms are differentially localized and regulated in GI tract and kidney.
