Abstract

In order to study the molecular aspects of albinism, we analyzed the expression of tyrosinase gene in some amelanotic mutant mice by Northern blotting using mouse tyrosinase cDNA as a probe. It hybridized with a species of 2.1 kilobase RNA prepared from the skin of wild-type mice and two albino strains in the same quantity. In black-eyed white mouse, however, no RNA transcript encoding tyrosinase was detected. Our results suggest that these albinism is due to a point mutation in the structural region of the tyrosinase gene, not to a deficiency of tyrosinase gene expression and that the black-eyed white mouse has a deficiency in the gene expression possibly related to melanocyte differentiation.
