A bacterial lacZ gene was inserted into the gene such that the endogenous gene promoter drives expression of beta-galactosidase. While RT-PCR analysis detects a gene transcript in all tissues analyzed, beta-galactosidase expression from this allele is detectable in brain and testis. Comparing RT-PCR with lacZ data suggests that the lacZ reporter gene does not fully reflect the endogenous expression pattern.
