| molecularNote | A neomycin resistance cassette was inserted into the first coding exon, 60 bp downstream of the initiation codon. Northern blot analysis on RNA derived from various tissues of homozygous mice demonstrated that no transcript was produced from this allele. Activity assays and western blotting experiments confirmed that no functional protein was expressed. |
