The distribution of the P2x2 purinoceptor subunit protein, which forms ATP-gated ion channels by homo- and hetero-multimeric assembly, was examined in the adult rat and guinea-pig cerebellum using two novel antisera generated against separate 18 amino acid sequences located in the predicted extracellular domain of this subunit. These antisera, the first(More)
ADP-ribosylation factor (ARF) is a small molecular weight GTP-binding protein (20 kD) and has been implicated in vesicular protein transport. The guanine nucleotide, bound to ARF protein is believed to modulate the activity of ARF but the mechanism of action remains elusive. We have previously reported that ARF binds to Golgi membranes after Brefeldin(More)
Abscisic acid ((+)-ABA) is a phytohormone involved in the modulation of developmental processes and stress responses in plants. A chemical proteomics approach using an ABA mimetic probe was combined with in vitro assays, isothermal titration calorimetry (ITC), x-ray crystallography and in silico modelling to identify putative (+)-ABA binding-proteins in(More)
