Gene Affected ラット Gad1遺伝子
Origin Knockout rats in which the Gad1 gene was disrupted using the CRISPR/Cas9.
Strain characteristics Glutamate decarboxylase (GAD; there are two isoforms, GAD65 and GAD67) is an enzyme that synthesizes the neurotransmitter GABA. In this strain, the Gad1 gene encoding GAD67 was knocked out. In homozygous rats, low body weight at 3 weeks and impaired spatial learning memory were observed.
Breeding Conditions Some homozygous rats die as juveniles. This strain is maintained in heterozygotes.
Genotyping Genotyping using PCR.
