Generation Definitions
Donating InvestigatorDr. Arthur Beaudet,   Baylor College of Medicine

The Ube3a (ubiquitin protein ligase E3A or E6-AP) knockin allele has YFP (Yellow Fluorescent Protein) fused to exon 10 of the Ube3a locus. Due to imprinting, E6-AP:YFP is preferentially expressed from the maternal allele at high levels in cortical and hippocampal pyramidal neurons and at lower levels in Purkinje cells and cerebellar neurons. YFP expression from the paternal allele is only faintly detected in these cells. E6-AP:YFP is biallelicly expressed in the glial cells lining the lateral ventricles. The fusion protein localizes both to the nucleus and to presynaptic and postsynaptic compartments in cultured hippocampal neurons. These E6-AP:YFP mutant mice carry a maternally imprinted Ube3a (ubiquitin protein ligase E3A) knockin fluorescent reporter and may be useful in imaging studies of Angelman syndrome.

A cassette containing yellow fluorescent protein (YFP) and a loxP flanked neomycin resistance gene was fused to exon 10 of the targeted allele. The construct was electroporated into 129S7/SvEvBrd-Hprtb-m2 derived AB2.2 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. The resulting chimeric animals were backcrossed to C57BL/6 for at least 5 generations. Upon arrival at The Jackson Laboratory, the mice were crossed to C57BL/6J (Stock No. 000664) at least once to establish the colony.

Health & Colony Maintenance Information

Colony Maintenance

Breeding & HusbandryWhile maintaining a live colony, these mice are bred as heterozygotes. Due to imprinting, YFP is expressed preferentially through the maternal allele. The donating investigator indicates the homozygotes do not breed well.

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.
