The interpretation of genome sequences requires reliable and standardized methods to assess protein function at high throughput. Here we describe a fast and reliable pipeline to study protein function in mammalian cells based on protein tagging in bacterial artificial chromosomes (BACs). The large size of the BAC transgenes ensures the presence of most, if(More)
Protein interactions are involved in all cellular processes. Their efficient and reliable characterization is therefore essential for understanding biological mechanisms. In this study, we show that combining bacterial artificial chromosome (BAC) TransgeneOmics with quantitative interaction proteomics, which we call quantitative BAC-green fluorescent(More)
To assemble mitotic spindles, cells nucleate microtubules from a variety of sources including chromosomes and centrosomes. We know little about how the regulation of microtubule nucleation contributes to spindle bipolarity and spindle size. The Aurora A kinase activator TPX2 is required for microtubule nucleation from chromosomes as well as for spindle(More)
Although the acetylation of histones has a well-documented regulatory role in transcription, its role in other chromosomal functions remains largely unexplored. Here we show that distinct patterns of histone H4 acetylation are essential in two separate pathways of double-strand break repair. A budding yeast strain with mutations in wild-type H4 acetylation(More)
Whereas bacterial artificial chromosomes (BACs) offer many advantages in studies of gene and protein function, generation of seamless, precisely mutated BACs has been difficult. Here we describe a counterselection-based recombineering method and its accompanying reagents. After identifying intramolecular recombination as the major problem in(More)
With the widespread use of time-lapse data to understand cellular function, there is a need for tools which facilitate high-throughput analysis of data. We present a system for automated segmentation and mitotic phase labelling based on a wide margin discriminative Semi-Markov Model. This work takes the novel approach of using temporal features evaluated(More)
The regulation of cell migration is a highly complex process that is often compromised when cancer cells become metastatic. The microtubule cytoskeleton is necessary for cell migration, but how microtubules and microtubule-associated proteins regulate multiple pathways promoting cell migration remains unclear. Microtubule plus-end binding proteins (+TIPs)(More)
The molecular cloning and initial characterization of the complementary DNA encoding the chicken homologue of the human retinoblastoma susceptibility gene product Rb are described. Chicken Rb (chRb) was found to be highly homologous to human, mouse, and Xenopus Rb in primary amino acid sequence, underlining its conserved function in cell cycle control in(More)
With the widespread use of time-lapse data to understand cellular function, there is a need for tools which facilitate high-throughput analysis of data. Fluorescence microscopy of genetically engineered cell lines in culture can be used to visualise the progression of these cells through the cell cycle, including distinctly identifiable sequential stages of(More)
The detection of chromosome segregation errors in mitosis is an important area of biological research. Due to the rarity and subtle nature of such errors in untreated cell lines, there is a need for automated, high-throughput systems for quantifying the rates at which such defects occur. This paper presents a novel approach to detecting subtle chromosome(More)
