...Kirk A. Taylor; Joy R. Wright; Martyn P. Mahaut-Smith Pannexin-1 (Panx1) forms anion-selective channels with a permeability up to 1 kDa and represents a pathway for the release of cytosolic ATP. Several structurally similar connexin (Cx) proteins have been identified in platelets and shown to play...

..., the signalling pathways eliciting glycogen degradation inside astrocytes are themselves energy-demanding processes, a fact that has been emphasized in recent studies, demonstrating dependence of these signalling mechanisms on glycogenolytic ATP. 1 email mm889@cam.ac.uk 9 6 2014 © 2014...

..., which maintain the well-being and function of neurons. Still, the study of age-related changes in neuron–glia signalling is far from complete. We have shown previously that cortical astrocytes are capable of releasing ATP by a quantal soluble N -ethylmaleimide-sensitive factor-attachment protein...

... by the adenine ring of ATP. In the present paper, we show how the spine concept can be applied to B-Raf, specifically to engineer a kinase-dead pseudokinase. To achieve this, we mutated one of the C-spine residues in the N-lobe (N-terminal lobe), Ala 481 , to phenylalanine. This mutant cannot bind ATP...

...G.L. Ackland; V. Kasymov; A.V. Gourine The purine nucleotide ATP mediates several distinct forms of sensory transduction in both the peripheral and central nervous systems. These processes share common mechanisms that involve the release of ATP to activate ionotropic P2X and/or metabotropic P2Y...

...J.A. Eldred; J. Sanderson; M. Wormstone; J.R. Reddan; G. Duncan ATP release has been shown to occur following stimulation in several cellular systems. This study was undertaken to determine if lens and retinal epithelial cells release ATP in response to physiological stresses and to elucidate...
