Gene trapped (Reporter) | Git2 | G protein-coupled receptor kinase-interactor 2 |
A targeting vector containing β-galactosidase was randomly inserted downstream of exon 2 of the endogenous G protein-coupled receptor kinase-interactor 2 (Git2) gene. Homozygous mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This β-geo secretory trap mutation abolishes endogenous gene function and expresses a Git2-exon1-2/lacZ fusion protein. Git2 belongs to the family of ADP-ribosylation factor GTPase-activating proteins (ARF-GAP) and has been implicated in the regulation of G protein-coupled receptor sequestration, cell migration, T-cell activation, neuronal spine formation, and aggregate formation in Huntington's disease. GIT2 expression is seen throughout the liver, lungs, spleen, muscle, and the central nervous system. Expression of GIT2 is also seen during absent spermatid differentiation but is absent in mature spermatids. These mice may be useful as a lacZ reporter for Git2 expression.
A "secretory trap" targeting vector containing β-galactosidase was electroporated into 129P2/OlaHsd-derived E14TG2a.4 embryonic stem (ES) cells. This vector inserted downstream of exon 2 of the endogenous G protein-coupled receptor kinase-interactor 2 (Git2) gene. Correctly targeted ES cells were injected into C57BL/6 blastocysts, and chimeric mice were bred with C57BL/6 mice. These Git2(XG510) mice were backcrossed to BALB/c for at least 10 generations. Upon arrival at The Jackson Laboratory, mice were bred to BALB/cJ (Stock No. 000651) for at least one generation to establish the colony.

Strain of Origin | 129P2/OlaHsd |
Chromosome | 5 |
Molecular Note | A gene trap vetor containing a beta-geo cassette was inserted into intron 2. Insertion was confirmed by PCR genotyping and expression of the lacZ gene was confirmed by beta-galactosidase staining. Two transcripts were detected by RT-PCR: one the expected fusion of exon 1 and 2 to the gene trap vector sequence and the other an alternative transcript lacking exon 2. |

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.
