MGI:2655224 Grin1<tm1Slab> MGI:95819 Grin1
Heterozygous animals have subregion-specific impairment of hippocampal plasticity, associated with impaired spatial memory and navigation. Homozygeous animals (neo/neo) die shortly after birth. Heterozygous animals with heterozygous global Cre-mediated removal of the neo cassette (Grin1<tm1.1Slab>) die shortly after birth. Therefore the Grin1<tm1.1Slab> allele cannot be maintained. Contact

MGI:2655237 Grin1<tm2Slab> MGI:95819 Grin1
The allele behaves as a Grin1 null allele. Homozygous animals die shortly after birth. Grin1 expression may potentially be induced by tTA or rtTA. Knocked-in tTA DNA segment apparently inactive. Contact
