Donating InvestigatorDr. Zena L. Harris,   Johns Hopkins Univ School of Medicine

Description
Mice that are homozygous null for the Cp gene demonstrate a progressive accumulation of iron in hepatocytes and reticuloendothelial cells. By one year of age, iron content of the liver and spleen reaches three to six-fold that observed in wild-type litter mates. The Cp gene product appears to be necessary for proper iron efflux from these cell types. This strain represents a viable murine model for aceruloplasminemia. At one year of age there is no evidence of anemia, diabetes, or neurological symptoms despite iron accumulation at the corresponding tissue sites.

Development
The majority of exon 17 and exon 18 has been replaced with a neomycin cassette resulting in the generation of an unstable mRNA.

Mutation Made ByDr. Zena Harris,   Johns Hopkins Univ School of Medicine
Strain of Origin129X1/SvJ
ES Cell Line NameRW-4
ES Cell Line Strain129X1/SvJ
Gene Symbol and Name Cp, ceruloplasmin
Chromosome 3
Gene Common Name(s) CERP; CP-2; D3Ertd555e; DNA segment, Chr 3, ERATO Doi 555, expressed;
Molecular Note A neomycin resistance cassette replaced a genomic fragment containing part of exon 17, intron 17 and part of exon 18, which include sequences encoding the residues essential for the formation of the trinuclear copper cluster of the encoded protein. Western blot analysis on serum derived from homozygous mice demonstrated that no detectable encoded protein was present, and activity assays on serum of homozygous mice confirmed that no functional protein is made from this allele.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
