The mouse Nlrc4 cDNA with a mutation equivalent to the human A to C transversion at position 1589 in exon 4 (changing a histidine to a proline at position 443) and three HA tags is under the control of an invariant chain promoter. Three lines were created: 1, 2, and 3. Line one shows an approximate 3.1-fold increase in Nlrc4 levels in the spleen compared to endogenous levels.
