We summarize the studies and discussions of the Structure Function subgroup of the QCD working group of the Snowmass 1996 Workshop: New Directions for High Energy Physics.
5-Hydroxytryptamine 2 (serotonin 2 , 5-HT 2 )-family receptors are important for mediating many physiological functions, including vascular and nonvascular smooth muscle contraction, platelet aggregation, modulation of perception, mood, anxiety, and feeding behavior. A large number of psychopharmaceuticals, including atypical antipsychotic drugs, antidepressants, anxiolytics, and hallucinogens,...
Primase is the ssDNA-dependent RNA polymerase that synthesizes RNA primers during DNA replication. In common with all DNA and RNA polymerases, primase has structural and functional features involved in polymer elongation. As RNA polymerase, it has structural and functional features for initiating chain synthesis. As a primase, it has structural and functional features for initiating chain synth...
Glycosphingolipids occur in most hi her organisms as 200 compounds in this class have been isolated and chemically characterized. In this aper, we compare the structures of several complex glycosphingoEpids and discuss the utilit of fast atom bombardment mass spectrometry in the MSldS mode with collision-assisted dissociation of the ceramide ion to study details of the ceramide structure. The f...
An understanding of the biochemical basis of membrane function is an important goal of present day biology. In this paper, a biochemical approach to the problem of the specific transport of sugars across the membrane of Escherichia coli is discussed. A new biochemical model for lactose transport system in this organism is presented, in which a specific membrane protein (M protein) plays the rol...
Marsden, J. (2004) Implications of and treatment options for retinal detachment. Nursing Times; 100: 37, 44–47. The retina is a complex structure that turns light falling onto it via a chemical reaction into nerve impulses, which then travel to the brain for interpretation into images. If the retina is damaged or moved from its correct location, a person’s ability to interpret the world is comp...
developmental sequences new types of abnormality, either hitherto un-described or published merely as rare and unexplained findings, can be understood and traced to their embryological sources." The discussion of anomalies is in terms of aberrant growth and disturbances of the growth sequence per se. Thus, although the preface states that "The ultimate cause of these slight local changes of gro...
Mutations in the parkin or PINK1 genes are the leading cause of the autosomal recessive form of Parkinson's disease. The gene products, the E3 ubiquitin ligase parkin and the serine/threonine kinase PINK1, are neuroprotective proteins, which act together in a mitochondrial quality control pathway. Here, we review the structure of parkin and mechanisms of its autoinhibition and function as a ubi...
Background. Studies done in potential donors for heart transplantation and in experimental animals have suggested that brain death can have major histopathological and functional effects on the myocardium. Methods and Results. We developed experimental models of brain death using dogs to study the hemodynamic and catecholamine changes, the extent of myocardial structural damage, and the recover...
Dnmt1, the principal DNA methyltransferase in mammalian cells, is a large and a highly dynamic enzyme with multiple regulatory features that can control DNA methylation in cells. This chapter highlights how insights into Dnmt1 structure and function can advance our understanding of DNA methylation in cells. The allosteric site(s) on Dnmt1 can regulate processes of de novo and maintenance DNA me...
