With the rapid growth of modern sequencing technology, more and more entire genomes have been completed, leading to an explosion of new gene sequence. Unfortunately, for most of these new sequences, we do not know any of their properties, such as their sub-cellular localizations. It is too time consuming to determine the properties of each sequence manually in a biological laboratory, since it typically takes months or even years to determine the properties of even a single protein sequence.

520 $a With the rapid growth of modern sequencing technology, more and more entire genomes have been completed, leading to an explosion of new gene sequence. Unfortunately, for most of these new sequences, we do not know any of their properties, such as their sub-cellular localizations. It is too time consuming to determine the properties of each sequence manually in a biological laboratory, since it typically takes months or even years to determine the properties of even a single protein sequence.
520 $a A much quicker alternative is to use computational techniques to make predictions in a high-throughput fashion. Proteome Analyst SUB-cellular localization server (PA-SUB) is a system that uses machine learning techniques to predict the sub-cellular localization of each protein in a proteome. This dissertation demonstrates how PA-SUB applies established machine learning techniques to make accurate predictions. It describes techniques and experiments that establish reliable training/testing datasets, significant feature extraction, efficient algorithm selection and convincing validation methods.
520 $a PA-SUB is described and the results of its application are presented along with concrete examples. Experiments are presented that compare different feature identification techniques and different classifier technologies. We obtained excellent results (approximately 90% 5-fold cross-validation accuracy) for sub-cellular localization prediction. These results are better than published results using other techniques. More generally, this dissertation demonstrates that computational machine learning techniques can be used effectively for the prediction of protein properties.
