Tpm3^tm1Pgun

A single loxP site remained in place of the first coding exon (1b) and the donor splice junction following the excision of a floxed neo cassette by transient Cre-mediated recombination. This mutation was designed to eliminate all non-muscle type isoforms of the encoded protein. Western blot showed that protein levels in heterozygote brains were the same as that of wild-type.
