Mutation detailsExon 6 was replaced with one containing a G to A transition within the splice donor site and a floxed neo cassette. Cre mediated recombination removed the neo cassette. RT-PCR detects three isoforms. Isoform mutant-1 contains the missense transition predicted to produce an E264K 150 KDa protein. Isoform mutant-2 and mutant-3 lack exon 6, inducing a frameshift. Isoform mutant-2 contains a premature termination codon in exon 9 (nonsense) and is predicted to produce a 32 KDa truncated protein, including 41 novel amino acids. Isoform mutant-3 retains 46 bp of intron 8 followed by a new cryptic acceptor splice site (deletion/insertion), which restores the reading frame and is predicted to produce a 147 KDa protein, containing an internal deletion and 41 novel amino acids. Isoform mutant-2 and -3 represent 50% of the total mRNA in homozygous mice. Western blot analysis detected all three predicted protein products. A greater than 80% reduction in total mRNA and protein levels was reported. (J:164934)
