Drebrin is an actin filament (F-actin)-binding protein with crucial roles in neuritogenesis and synaptic plasticity. Drebrin couples dynamic microtubules to F-actin in growth cone filopodia via binding to the microtubule-binding +TIP protein EB3 and organizes F-actin in dendritic spines. Precisely how drebrin interacts with F-actin and how this is regulated(More)
Meiosis, the developmental programme generating haploid gametes from diploid precursors, requires two cell divisions and many innovations. In budding yeast, a large number of genes are expressed exclusively during meiosis while others are repressed compared to vegetative growth. Microarray analysis has shown that gene expression during meiosis is highly(More)
Meiosis is the cell division that generates haploid gametes from diploid precursors. To provide insight into the functional proteome of budding yeast during meiosis, a 2-D DIGE kinetic approach was used to study proteins in the pH 6-11 range. Nearly 600 protein spots were visualised and 79 spots exhibited statistically significant changes in abundance as(More)
In meiosis, accumulation of recombination intermediates or defects in chromosome synapsis trigger checkpoint-mediated arrest in prophase I. Such 'checkpoints' are important surveillance mechanisms that ensure temporal dependence of cell cycle events. The budding yeast Polo-like kinase, Cdc5, has been identified as a key regulator of the meiosis I chromosome(More)
