The tyrosinase related protein-1 (Tyrp1) promoter in transgenic experiments: targeted expression to the retinal pigment epithelium.


Transgenic experiments targeting gene expression to the retinal pigment epithelium (RPE) require use of a pigment cell-specific promoter. We have chosen 1.4 kb and 4 kb from the promoter of the tyrosinase-related protein 1 gene (Tyrp1) for RPE-specific expression, since Tyrp1 mRNA and protein are detected already at midgestation in this epithelial layer.
