mouse strain Insm1{tm1.1Mgn} mouse strain A mouse strain in which part or all of the targeted gene, insulinoma-associated 1 (NCBI Gene ID: 53626) is replaced to create Insm1{tm1.1(GFP-Cre)} using the Loxed Cassette Acceptor allele Insm1{tm1(LCA)}). <p>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 theInsm1gene 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.</p> Insm1{tm1.1Mgn} Person: Mark A.
