Vacuolar-vesicular protein sorting (Vps) factors are involved in vesicular trafficking in eukaryotic cells. We identified the missense mutation L967Q in Vps54 in the wobbler mouse, an animal model of amyotrophic lateral sclerosis, and also characterized a lethal allele, Vps54(beta-geo). Motoneuron survival and spermiogenesis are severely compromised in the(More)
Short treatment of HeLa cells with cyclosporine A led to the activation in the crude cell extracts of a MAP kinase-like activity. Fractionation by chromatography on a Mono Q column allowed the separation of two activities co-eluting with the MAP kinases ERK1 and ERK2. The activation of these two MAP kinases was demonstrated in Western Blotting by the(More)
This chapter describes a transient protoplast co-transfection method that can be used to quantitatively study in vivo the activity and function of promoters and promoter elements (reporters), and their induction or repression by transcription factors (effectors), stresses, hormones, or metabolites. A detailed protocol for carrying out transient(More)
