  • This targeted mutation strain carries a replacement of the mouse Abcc2 gene which encodes for the multidrug resistance protein (MRP2) with the corresponding human orthologous gene.
  • Useful to study the role of human MRP2 in drug bioavailability.


The Humanized MRP2 Mouse was developed by Taconic in collaboration with CXR Biosciences. It was created through a targeted replacement of mouse Mrp2 Exon 2 with a cDNA construct containing human MRP2 Exons 2-32 in C57BL/6NTac-derived ES cells. This leads to the expression of a fusion protein of amino acids encoded by mouse Exons 1 and human Exons 2 to 32 driven by the mouse Mrp2 promoter, so that the potential mouse leader sequence encoded by Exon 1 is retained. Targeted ES cells were injected into BALB/cJBomTac blastocysts and the resultant chimeras were backcrossed to a Flpe deleter strain on C57BL/6J to eliminate the selection marker. Taconic received stock in 2009, and the line was embryo transfer derived. The colony was maintained by mating homozygotes.
