Mutations in leucine-rich repeat kinase 2 (LRRK2) comprise the leading cause of autosomal dominant Parkinson's disease, with age of onset and symptoms identical to those of idiopathic forms of the disorder. Several of these pathogenic mutations are thought to affect its kinase activity, so understanding the roles of LRRK2, and modulation of its kinase(More)
BACKGROUND Between March 2003 and June 2007, our burn center received 594 casualties from the conflicts in Iraq and Afghanistan. Ongoing acute burn resuscitation as severely burned casualties are evacuated over continents is very challenging. To help standardize care, burn resuscitation guidelines (BRG) were devised along with a burn flow sheet (BFS) and(More)
IL12 (formerly NKSF or CLMF) is a unique cytokine composed of two unrelated disulfide-linked subunits. The larger 40-kDa subunit (p40) is a member of the cytokine receptor family, and the smaller 35-kDa subunit (p35) is related to IL6 and GCSF. The chromosomal localization of these two subunits was determined by PCR analysis of DNA from rodent-human(More)
A fluorescence polarization competition assay has been developed to screen for inhibitors of the Escherichia coli FtsZ/ZipA protein-protein interaction. A previously published X-ray costructure demonstrated that a 17-amino-acid peptide, corresponding to FtsZ C-terminal residues 367-383 (FtsZ(367-383)), interacts with the C-terminal FtsZ binding domain of(More)
We report a flexible strategy for the high level expression of a recombinant human monoclonal antibody (mAb) in Chinese hamster ovary (CHO) cells, initially using COS monkey kidney cell transfections to evaluate rapidly modifications to immunoglobulin (Ig) DNA constructs. Using sequential transfections with two amplifiable markers, we generated CHO cell(More)
When the 34 kDa kinase domain of human spleen tyrosine kinase (Syk-KD) was expressed as a C-terminally His-tagged protein in baculovirus-infected Sf-21 insect cells, the purified protein included two forms that migrated slightly differently in SDS-polyacrylamide gel electrophoresis. Intact mass analysis and LC-MS/MS peptide mapping showed that the major and(More)
Nogo receptor (NgR)-mediated control of axon growth relies on the central nervous system-specific type I transmembrane protein Lingo-1. Interactions between Lingo-1 and NgR, along with a complementary co-receptor, result in neurite and axonal collapse. In addition, the inhibitory role of Lingo-1 is particularly important in regulation of oligodendrocyte(More)
Phosphorylation of inhibitor of nuclear transcription factor κB (IκB) by IκB kinase (IKK) triggers the degradation of IκB and migration of cytoplasmic κB to the nucleus where it promotes the transcription of its target genes. Activation of IKK is achieved by phosphorylation of its main subunit, IKKβ, at the activation loop sites. Here, we report the 2.8 Å(More)
Dissociated dorsal root ganglion cells (DRGs), taken from rats 2 weeks after sciatic nerve transection, have an increase in the percentage of cells with neurites compared to DRGs taken from normal animals. This study examines the possible factors that may contribute to the nerve injury-induced increase in neuritogenesis. Topical application of the local(More)
Previous evidence, from both crystallographic and biochemical studies, has indicated that profound tertiary and quaternary changes in the structure of Escherichia coli aspartate transcarbamylase occur upon the binding of the bisubstrate analogue N-(phosphonoacetyl)-L-aspartate (PALA). In particular, within a single catalytic polypeptide chain, the aspartate(More)
