Mutation detailsA PGK-neomycin resistance cassette replaced a 0.28 kb genomic fragment that contained the translation start site and the region coding for the first 54 amino acids of the encoded protein. Immunoprecipitation studies demonstrated that no detectable protein was present in membranes prepared from hippocampus of homozygous mice. (J:74588)
