PKL12 (STK16) is a ubiquitously expressed Ser/Thr kinase, not structurally related to the well known subfamilies, with a putative role in cell adhesion control. Yeast two-hybrid protein interaction screening was used to search for proteins that associate with PKL12 and to delineate signaling pathways and/or regulatory circuits in which this kinase(More)
Although double-stranded (ds) RNA viruses are a rather diverse group, they share general architectural principles and numerous functional features. All dsRNA viruses, from the mammalian reoviruses to the bacteriophage phi6, including fungal viruses, share a specialized capsid involved in transcription and replication of the dsRNA genome, and release of the(More)
To function adequately, many if not all proteins involved in macromolecular assemblies show conformational polymorphism as an intrinsic feature. This general strategy has been described for many essential cellular processes. Here we describe this structural polymorphism in a viral protein, the coat protein of Rabbit hemorrhagic disease virus (RHDV), which(More)
Expression of pathogenesis-related (PR) genes is part of the plant's natural defense response against pathogen attack. To study the in vivo role and function of the maize PRms protein, tobacco plants were transformed with the PRms cDNA under the control of the CaMV35S promoter. Transgenic tobacco plants grow faster and yield more leaf and seed biomass. By(More)
This study describes three novel homozygous missense mutations (S75R, S201Y, and D204N) in the 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) lyase gene, which caused 3-hydroxy-3-methylglutaric aciduria in patients from Germany, England, and Argentina. Expression studies in Escherichia coli show that S75R and S201Y substitutions completely abolished the HMG-CoA(More)
Signaling by receptor protein kinases (RPKs) involves their dimerization and transphosphorylation. However, atypical RPKs with kinase-defective domains have been described recently. Some of them are essential for proper signaling in animal systems, although the precise mechanism involved is unknown in most cases. Here we describe the cloning and(More)
The G protein-coupled receptor (GPCR) kinase GRK2 phosphorylates G protein-coupled receptors in an agonist-dependent manner. GRK2 activity is modulated through interactions of diverse domains of the kinase with G protein betagamma subunits, several lipids, anchoring proteins, and activated receptors. We report that kinase activity toward either GPCR(More)

A novel series of aminopyridine N-oxides were designed, synthesized, and tested for their ability to inhibit p38alpha MAP kinase. Some of these compounds showed a significant reduction in the LPS-induced TNFalpha production in human whole blood. Structure-activity relationship studies revealed that N-oxide oxygen was essential for activity and was probably(More)
