G2CMine integrates the scientific findings of the Genes to Cognition Programme that utilised neuroproteomics, psychiatric genetics, high-throughput mouse gene targeting combined with behavioural and electrophysiological phenotyping and informatics in order to develop a general strategy for understanding cognition at the molecular, cellular and systems neuroscience levels.
G2CMine provides comprehensive Gene Ontology, Mammalian Phenotype Ontology, Human Phenotype Ontology, UniProt, genetic and protein interactions, and regional mouse brain expression results, together with the phenotyping results of the G2C Programme.
Mutation
E14TG2a mouse embryonic stem (ES) cells were targeted with a vector containing 6.8kb and 3.2kb of flanking genomic DNA. This replaced 945bp of Agap2 genomic DNA (X126520053 to X126520998; Ensemble Build 50) with IRES-lacZ-neo cassette. Correctly targeted ES cells were identified by long range PCR using Expand Long Template PCR system (Roche Cat 11681842001). The PCR contained primer X (5’-GAGCTATTCCAGAAGTAGTGAG-3’) and primer Y (5’- GTTTCCCAGTGTGACTGTCTC -3’) that correspond to sequence in the IRES-lac-Zneo cassette and sequence outside the 3.2kb flanking region respectively.
The correctly targeted ES cells were injected into C57BL/6 blastocysts to create chimeric mice, which were bred with 129S5 mice to generate heterozygous (+/–) Agap2 mutant mice. Those F1 heterozygous mice had been backcrossed with 129S5 mice for 1-2 times before being used for intercrossing.
Location of Agap2 gene trap. Agap2 is a 19 exon gene which encodes Ras GTPase, PH, ArfGAP and ANK domains (top). We replaced Agap2 exons 4 and 5 with a selection cassette in targeted mice and created a frameshift between exons 3 and 6. Primers used for targeted clone identification (x&y) are shown.
Genotyping
Genomic DNA was isolated from ES cells by Wizard SV 96 Genomic DNA purification system (Promega Cat A2371). Genotyping PCR consisted of a 356bp product amplified from the wild-type (wt) allele using a forward primer A (GTTCACATTGCCATTTCTGAC) in the wt sequence deleted by targeted mutation and a reverse primer B (GGAGAACAATGAGAGGTGAAC) downstream of the cassette. A 501bp product was amplified from the targeted allele using primer B with forward primer X, within the selection cassette. After enzymatic amplification for 35 cycles (45 seconds at 94 °C, 45 seconds at 55 °C, and 1 minute at 72 °C), the PCR products were size-fractionated on a 2% agarose gel in 1x Tris borate-EDTA buffer.

Breeding
Birth of PIKE-/- mice followed Mendelian ratios with 20% of offspring being homozygous knockouts. Genotypes of 3-week-old pups from PIKE+/- intercrosses identified 70 wt, 170 PIKE+/- and 63 PIKE-/- progeny (Χ2 p= 0.089). Male and female PIKE-/- mice developed normally to adulthood, exhibited normal body size and no gross abnormalities. PIKE mice were maintained by backcrossing onto the 129S5/SvEvBrd background; heterozygous males and females were fertile and used to set up intercrosses to generate homozygous and wildtype mice to study.
Overview
Mutant mice showed little overall behavioural difference from wildtypes, with three of 16 behaviour variables significantly impacted in these mutants. In the open field/novel object exploration task, two behavioural variables of two were significantly impacted in mutants. In the contextual memory task, one behavioural variable, contextual memory change, was significantly decreased in mutants. Elevated plus maze, rotarod, fear learning and cued memory tasks were unaffected. Definitions of variables may be found below.
