(A) Maps of the Cadps2 gene, the targeting
vector, and the resultant targeted allele are shown. Probes for Southern
blot analysis to screen for targeted ES clones are indicated by small solid
bars. Restriction enzyme sites include the following: B,
BamHI; E1, EcoRI; E5,
EcoRV; S, SmaI; X, XhoI.
DTA, diphtheria toxin A fragment (B) Southern blot analysis,
using the probes indicated in A, of DNA from tails of a single
litter derived from a cross between heterozygotes. +/+, WT mice;
+/–, heterozygous mice; –/–, homozygous
mice. (C) RT-PCR banding patterns of CADPS2 using brain total
RNA of P21 WT, heterozygous, and homozygous mice. The GAPDH
gene was used as a constantly expressed control mRNA. (D)
Immunoblot analysis of the cerebellum, neocortex, and hippocampus of P8 WT,
heterozygous, and homozygous mice. Protein lysates from these brain regions
were immunoblotted with anti-CADPS2 antibody. Cb, cerebellum; Cx, neocortex;
Hip, hippocampus.
