| molecularNote | Part of exon 1 and intron 1 were replaced by an IRES-lacZ reporter gene followed by a floxed PGK-neo cassete. PGK-neo was excised in vivo by crossing carriers with NLS-Cre transgenic mice which express cre ubiquitously. Western blot analysis indicated that the protein product was not produced. |
