title: Mash-1 is expressed during ROD photoreceptor differentiation and binds an E-box, E(opsin)-1 in the rat opsin gene.
abstract: It has been shown previously that the transcription factor Mash-1 plays a significant role in mammalian neurogenesis. In the present study we show that Mash-1 is expressed during rat retinal development and that it interacts specifically with an E-box identified in the promoter of the opsin gene during rod photoreceptor differentiation. We propose that opsin may be one of the downstream neuronal genes regulated by Mash-1 during neurogenesis in the central nervous system.
