Members of the SNF1-related protein kinase-1 (SnRK1) subfamily of protein kinases are higher plant homologues of mammalian AMP-activated and yeast SNF1 protein kinases. Based on analogies with the mammalian system, we surmised that the SnRK1 kinases would be regulated by phosphorylation on a threonine [equivalent to Thr175 in Arabidopsis thaliana SnRK1(More)
We resolved from spinach (Spinacia oleracea) leaf extracts four Ca2+-independent protein kinase activities that phosphorylate the AMARAASAAALARRR (AMARA) and HMRSAMSGLHLVKRR (SAMS) peptides, originally designed as specific substrates for mammalian AMP-activated protein kinase and its yeast homolog, SNF1. The two major activities, HRK-A and HRK-C(More)
The cost of psychiatric illness to the UK economy was recently estimated at pound77 billion annually. Despite years of research no firm aetiological explanation exists, and with no physiological or biochemical markers diagnosis is made entirely on a behavioural basis. All current pharmacological therapies are associated with serious long-term side effects.(More)
Korean Protestantism can be characterized as the rapid church growth and the emergence of the mega-churches, which attracts the focus of scholarly investigation. The number of Protestant churches increased from 3,279 in 1920 to 5,011 in 1960 and to 33,897 in 1996. The Protestant population in Korean society has grown significantly since the 1960s. As can be(More)
Differentiation-inducing factor-1 (DIF-1) is a polyketide that induces Dictyostelium amoebae to differentiate as prestalk cells. We performed a global quantitative screen for phosphorylation changes that occur within the first minutes after addition of DIF-1, using a triple-label SILAC approach. This revealed a new world of DIF-1-controlled signaling, with(More)
Since the government introduced the loan scheme for university students in 1990, it has become abundantly apparent that students are falling increasingly into debt. This paper describes the results of two studies undertaken by Manchester undergraduate dental students into the level and consequences of debt on dental students.
Tobacco use has become the leading cause of preventable death in Tonga, a small island nation in the South Pacific. One pragmatic and economical strategy to address this worrying trend is to adapt effective antitobacco mass media materials developed in high-income countries for local audiences. Using Tonga as an example, this paper shares the practical(More)
DIF-1 (differentiation-inducing factor1) is a polyketide produced by Dictyostelium prespore cells which induces initially uncommitted cells to differentiate as prestalk cells. Exposure of cells to DIF-1 causes transitory hypo-phosphorylation of seven serine residues in YelA, a protein with a region of strong homology to the MIF4G domain of the eukaryotic(More)
