|Gene symbol and name||Grpr(gastrin releasing peptide receptor), GR; GRP-R|
|Strain of origin||
|Coat color||Black||Dietary information||Growth and reproduction diet for experimental mice|
NCBI Gene ID
iCre, improved cre recombinase, bacteriophage P1
Site of expression
mouse Grp is highly expressed both in the lateral nucleus of the amygdala, the nucleus where associations for pavlovian learned fear are formed, and in the regions that convey fearful auditory information to the lateral nucleus.
Gene editing strategy
An F2A-iCre sequence cassette was placed between the coding sequence of exon 3 and 3’UTR of the Grpr gene in C57BL/6 ES cells. This strain was maintained on a C57BL/6 genetic background.
