This strain may be useful for generating conditional mutants for applications related to cognition and social dysfunction. Inserted loxP sites flank exons 3 to 6 of the Rapgef3 (Rap guanine nucleotide exchange factor 3) gene, an intracellular receptor for cyclic AMP.

RAPGEF3 (or EPAC1) is a rap guanine nucleotide exchange factor that functions as an intracellular receptor for cyclic AMP. Epac1 mRNA exhibits widespread expression. These mutant mice possess loxP sites flanking exons 3 to 6 of the (Rapgef3) gene. Mice that are homozygous for this allele are viable and fertile. When bred to mice that express Cre recombinase, the resulting offspring will have exons 3-6 deleted in the cre-expressing tissues. When a global Rapgef3 knockout is combined with Rapgef4Gt(OST450264) (Epac2 KO) (Stock No. 018390), double homozygous knockout mice exhibit impaired long term potentiation (LTP), deficits in spatial learning, memory deficits, and abnormal social interactions.
A targeting vector was designed to insert a loxP site upstream of exon 3 followed by a frt-flanked neomycin resistance (neo) cassette, and a second loxP site downstream of exon 6. The construct was electroporated into 129S2/SvPas-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and resulting chimeric mice were bred to C57BL/6 mice. Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J inbred mice (Stock No. 000664) for at least one generation to establish the colony.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
