Reticalmin: a novel calcium/calmodulin-dependent protein kinase IV-like protein in rat retina.

abstract：:The eyespots in cells of streptomycin-bleached strains and of dark-grown cultures of Euglena gracilis, were examined by means of fluorescence microscopy and microspectrophotometry. When viewed with light in the region of 380-500 nm, the stigma appeared as a dark spot. Adjacent to this was a second spot, not seen with ...
