CD1.129S6(Cg)-Insm1tm1.1Mgn

Insm1{GFPCre} mice contain a GFP-Cre fusion protein which replaces the Insm1 coding sequence. These mice express green fluorescent protein (GFP) under control of the Insm1 gene locus. Insm1 is expressed in pancreatic primordium starting at E9.5. Insm1 is also expressed in neural precursor cells and tumors of may be used for lineage tracing of Insm1-positive cells in both wild-type and Insm1-null mice.

Genetic Alteration

Mutation #1: RMCE Targeted Mutagenesis
Type of AlleleGene Replacement
Targeted GeneName: insulinoma-associated 1
Symbol: Insm1
NCBI: 53626
Allele Name: targeted mutation 1.1
Symbol: Insm1tm1.1(GFP-Cre)
Description of Targeting Vector

Through recombinase-mediated cassette exchange in ES cells, a 5232 bp fragment containing a GFP-Cre fusion gene was inserted into the Insm1 locus replacing the entire coding sequence of Insm1 gene. To facilitate positive selection of cassette-exchanged ES cells, a Pgk-Hygro selection cassette flanked by FRT sites was placed immediate downstream of the GFP-Cre fusion gene.
