The majority of Rab proteins are posttranslationally modified with two geranylgeranyl lipid moieties that enable their stable association with membranes. In this study, we present evidence to demonstrate that there is a specific lipid requirement for Rab protein localization and function. Substitution of different prenyl anchors on Rab GTPases does not lead(More)
Duchenne muscular dystrophy (DMD) is the most common and the most severe of the muscular dystrophies in man. It is inherited as an X-linked recessive trait and is characterized by ongoing necrosis of skeletal muscle fibres with regeneration and eventually fibrosis and fatty infiltration. Although the gene and gene product which are defective in DMD have(More)
We have characterized the mutation in a feline model of DMD that selectively eliminates expression of the muscle and Purkinje neuronal dystrophin isoforms. The cortical neuronal isoform was expressed at a detectable level in skeletal muscle in the absence of the muscle promoter and levels of PCR products representing cortical neuronal-type transcripts in(More)
Hereditary myotonia caused by mutations in CLCN1 has been previously described in humans, goats, dogs, mice and horses. The goal of this study was to characterize the clinical, morphological and genetic features of hereditary myotonia in Murrah buffalo. Clinical and laboratory evaluations were performed on affected and normal animals. CLCN1 cDNA and the(More)
Muscarinic activation of bovine tracheal smooth muscle (BTSM) is involved in cyclic guanosine monophosphate (cGMP) production mediated through soluble (sGC) and membrane-bound (mGC) guanylyl cyclases. A muscarinic- and NaCl-sensitive mGC exists in BTSM regulated by muscarinic receptors coupled to G proteins. To identify the mGCs expressed in BTSM, reverse(More)
