A gene trap vector inserted between the exons that encode the spectrin repeat 12 of the protein. Northern blot analysis demonstrated that a fusion transcript was expressed that consisted of the gene sequences and the beta-galactosidase gene of the vector. Western blot analysis on brain lysates of homozygous mice demonstrated that no detectable full length protein was made from this allele. (J:77228)
