These mice have the Ple49-lacZ transgene targeted as a single copy "knockin" into the upstream region of the Hprt locus on the X chromosome. The promoter/regulatory regions of the human DBH gene direct expression of β-galactosidase.

General Note | Germ line transmission of mutant cell line mEMS3682 has been established. |
Molecular Note | The Ple49-lacZ transgene (pEMS1520) was designed with the 756 bp Ple49 minipromoter (DBH-B; derived from a subsection of the promoter and an upstream putative regulatory element of the human dopamine beta-hydroxylase (dopamine beta-monooxygenase) [DBH] gene) upstream of a frt-flanked beta-galactosidase (lacZ) gene, an SV40 early polyA signal, and a human HPRT complementary sequence (containing exon1, intron1, exon2, and part of intron2). This construct was targeted as a single copy knockin to the Hprtb-m3 mutant locus on the X chromosome. The promoter/regulatory regions of the human dopamine beta-hydroxylase (DBH) gene directs expression of beta galactosidase (lacZ) to the noradrenergic cells in the locus coeruleus, with strong expression in the adrenal gland where it is coexpressed with tyrosine hydroxylase. |

The donating investigator recommends maintaining this strain by breeding heterozygous females with C57BL/6J inbred males (Stock No. 000664).

Facility Barrier Level Descriptions
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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
