The Dictyostelium rbrA gene encodes a putative Ariadne ubiquitin ligase. rbrA- cells form defective slugs that cannot phototax. Prestalk cell numbers are reduced in rbrA- slugs, and these prestalk cells do not localize to the tip of slugs. Chimeric slugs containing wild-type cells could phototax and form fruiting bodies.
