Former Common name GIPR Knockout mice
H-2 Haplotype No Data
Donor strain 129P2/Ola via CGR8 ES cell line
Background strain C57BL/6NCrSlc
1 Appearance black

Strain development Developed by Dr. Yutaka Seino, Kyoto University in 1999. A neomycin cassette was inserted to replace exons 4 and 5 of GIPR gene. The mutant mice were backcrossed to C57BL/6.
Strain description B6.129P2-Gipr<tm1Yse>. Gastric inhibitory polypeptide (GIP) is a gastrointestinal peptide hormone synthesized by K cells in the duodenum and small intestine, GIP plays a role in gastric secretory inhibition, gastric mobility, and insulin release by binding to its specific receptor, the GIP receptor (GIPR). Homozygous mutant mice for Gipr<tm1Yse> targeted mutation are fertile and viable, but exhibit hyperglycemia after high-fat diet ingestion. This strain is useful for elucidating of the signaling mechanism of GIP from pancreatic beta cell to intestine.
Colony maintenance Backcross to C57BL/6 (Heterozygote x C57BL/6CrSlc)
Homozygous mice are fertile and viable.
