Characterization of TRP-1 mRNA levels in dominant and recessive mutations at the mouse brown (b) locus.


The mouse brown locus encodes a putative membrane-bound metalloenzyme, tyrosinase-related protein-1 (TRP-1). We have examined the effect on mRNA expression of the locus of a number of mutant alleles. The common null mutant allele, brown, produces wild-type levels of TRP-1 mRNA, which is nonfunctional. Another recessive allele, cordovan-Harwell, has an… (More)
