Abstract

The calphotin protein, encoded by the calphotin (cap) gene, is expressed in the soma and axons of all Drosophila photoreceptor cells. It is expressed early in photo-receptor cell development, at the time when cell-type decisions are being made. Expression of calphotin is not altered by the glass mutation, which blocks photoreceptor cell development. The calphotin protein binds calcium and contains a long C-terminal leucine zipper. Potential implications of these properties are discussed.
