    Notes: Abstract: The Ret 1 element, located at −136 to −110 in the rat opsin promoter, binds developmentally regulated retinal nuclear proteins. A similar sequence is found upstream of opsin genes, from humans to Drosophila, as well as many other photoreceptor-specific genes. The function of the Ret 1 element was tested both in vitro and in two sets of transgenic mice. A mutated Ret 1 element did not bind retinal nuclear proteins in vitro. The same mutations in an otherwise normal 1.9-kb rat opsin promoter failed to drive expression of a lacZ reporter gene in nine of 12 lines. In the three other lines, expression in photoreceptors was very faint. Four tandem copies of the Ret 1 element maintained the Ret 1 binding specificity in vitro and were able to direct expression of a lacZ transgene in photoreceptors of all nine mouse lines obtained. In two lines, expression was also detected in the ganglion cell layer and the ciliary epithelium. In three lines, a characteristic pattern of expression was found in the nervous system in addition to the normal retinal expression. These results indicate that Ret 1 can and is necessary to drive gene expression in rod photoreceptors. Furthermore, our results suggest that Ret 1-like elements may also be important in the developing nervous system.

    Notes: Abstract: The G protein transducin (T) is an integral component of the signal transduction pathway in photoreceptors. We have identified a cis-acting element, Ta-1, in the upstream region of the mouse rod a-T (Trα) gene that may be important for tissue-specific expression. Tα-1 binds a retina-specific nuclear factor of apparent molecular mass of 90 kDa. Binding to the Tα-1 site is developmentally regulated and peaks between postnatal days 6 and 9. This corresponds to the time of rod photoreceptor maturation and the rise in Trα gene expression. The sequence of Tα-1 shows homology with RET-1, a cis-acting element in the proximal promoter of opsin gene that binds a distinct retina-specific factor. Tα-1 and RET-1 sequences may have been derived from a prototype Tα-1/RET-1 sequence, evolved to confer photoreceptor specificity on retina-specific genes.
