Reversible events in the transduction process of photoreceptors.

abstract：:In Dictyostelium discoideum, carbohydrate binding proteins (CBPs) or lectins have been implicated in the molecular basis of cellular cohesion. To determine the role of these CBPs, we have attempted to isolate structural gene mutants in which the CBPs have a defective affinity for carbohydrate ligands. We now report th...
