Pierre Thibault (IRIC, Chemistry); Maria Marcantonio (IRIC, Biochemistry); Matthias Trost (IRIC, Biochemistry); Laure Voisin (IRIC, -); Sylvain Meloche (IRIC, Pharmacologie); |
Short Abstract: Considering the wealth of information generated by large-scale phosphoproteomics experiments, novel and improved bioinformatics tools are now required to profile changes in phosphorylation and associate interacting partners involved in specific signaling cascade events. To this end, we developed a bioinformatics platform tailored to address the pressing needs of phosphoproteomics analyses. |

A Bayesian approach for protein inference problem in shotgun proteomics |
Yong Li- Indiana University - Bloomington |
Haixu Tang (Indiana University - Bloomington, School of Informatics); Predrag Radivojac (Indiana University - Bloomington, School of Informatics); Randy Arnold (Indiana University - Bloomington, Department of Chemistry); |
Short Abstract: We present a Bayesian approach which incorporates peptide detectability to solve the protein inference problem with high accuracy. The algorithm has better performance than other methods and it can effectively assign proteins with degenerate detected peptides. Besides, it also improves peptide identification. |

Spatial Querying of Imaging Mass Spectrometry Data |
Raf Van de Plas- K.U.Leuven |
Kristiaan Pelckmans (K.U.Leuven, Electrical Eng. ESAT-SCD); Bart De Moor (K.U.Leuven, Electrical Eng. ESAT-SCD); Etienne Waelkens (K.U.Leuven, Molecular Cell Biology); |
Short Abstract: Imaging mass spectrometry or mass spectral imaging (MSI) is a technology that adds a spatial dimension to mass spectrometry-based biochemical analysis. This work develops an efficient computational method that enables the researcher to interrogate MSI data from a spatial standpoint, rather than with traditional mass-centric approaches such as ion images. |

Specificity and cross-reactions in PDZ interaction networks |
David Gfeller- University of Toronto |
Gary Bader (University of Toronto, Donnelly Centre for Cellular and Biomolecular Research); |
Short Abstract: PDZ domains play a central role in protein interactions. We use phage display results to investigate how binding specificity is achieved. In particular, we focus on proteins that are predicted to interact with more than one domain to characterize the overlap between the binding regions of different PDZ domains. |

Assessment of ‘Golden Pair’ rule for peptide sequencing and protein identification using iontrap CAD/ETD MS/MS |
Thomas Hansen- University of Southern Denmark |
Ole Nørregaard Jensen (University of Southern Denmark, Department of Biochemistry and Molecular Biology); Frank Kjeldsen (University of Southern Denmark, Department of Biochemistry and Molecular Biology); |
Short Abstract: From corresponding low-resolution MS/MS spectra fragmented using CAD and ETD respectively, we extract 'Golden Pairs' of the same fragment ions of different types. These pairs are used in three different methods to remove false positive peptide identifications and thereby increase the confidence in protein identifications. |

Short Abstract: We applied differential proteomics methods to identify yeast chromatin associated proteins including cell cycle and chromatin remodeling proteins. This methodology, employing chromatin fractionation and DIGE screening, demonstrates the utility of proteomics mapping and quantification of low abundance chromatin associated proteins. |

Measuring phylogenetically deep conservation in protein sequences |
Sergey Mokin- McGill University |
Paul Harrison (McGill University, Biology); |
Short Abstract: We have derived novel methods for assessing significant violation of phylogenetically deep conservation in protein sequences. We have applied these methods to the characterization of pseudogenes and evolutionarily young sequences. The methods can demonstrate a significant loss of long-standing purifying selection in these sequences, where other algorithms cannot. |

Morten Källberg- University of Illinois at Chicago |
Hui Lu (University of Illinois at Chicago, Bioengineering); |
Short Abstract: We present a machine learning solution for classification of MS/MS database search results, improving on published performance by 6% (net prediction). Furthermore, we suggest a straight-forward way for extending this solution from the peptide prediction problem into the protein prediction problem and identified 80% of the proteins in the sample. |

Michael Gribskov- Purdue University |
Greg Ziegler (Purdue University, Department of Biological Sciences); |
Short Abstract: We have been analyzing serine, threonine, and tyrosine containing sequences in entire proteomes, and by a datamining process identifying subsequences that are likely to be protein kinase targets. Preliminary results have validated some of our early predictions for calcium dependent protein kinases in Arabidopsis. |

The Universal Similarity Metric applied to Protein Contact Map Comparison in a two dimensional Space |
Sara Rahmati- Queen's University |
Janice Glasgow (Queen's University, Computing); |
Short Abstract: We present an approach to compare protein contact maps by means of the Universal Similarity Metric in their matrix format. Without loss of any information in converting the dimensionality of the maps, our method shows noise tolerance which makes it applicable in several comparison applications in bioinformatics and proteomics. |

EigenMS: LC-MS spectral peaks SVD-based normalization tool |
Yuliya Karpievitch- Texas A&M |
Alan Dabney (Texas A&M, Statistics); |
Short Abstract: EigenMS is an open source graphical singular value decomposition based LC-MS data normalization tool. EigenMS estimates systematic biases by eigenpeptides computed on QC proteins, then subtracts the estimated eigenpeptides from the experimental samples. When QC proteins are unavailable, EigenMS can be applied directly to experimental samples in well-designed experiments. |

Short Abstract: We describe an improved method to determine and link accurate mass tag windows, which uses various types of MS level information to improve an initial alignment. We show how improving the alignment of distant ion maps will facilitate the comparison of complex proteomes by decreasing the influence of chromatographic variability. |
