Gene trap vector pGTO-fs inserted into the gene, included a beta galactosidase gene was inserted in intron 12. Resulting mice express a mutant protein composed of several hundred N-terminal amino acids fused to beta-galactosidase. This is a hypomorphic allele and wild-type mRNA is detectable in homozygotes by RT-PCR. (J:87046)
