Most methods annotating protein function utilise sequence homology to proteins of experimentally known function. Such a homology-based annotation transfer is problematic and limited in scope. Therefore, computational biologists have begun to develop ab initio methods that predict aspects of function, including subcellular localization, post-translational(More)
The identification of genetic and epigenetic alterations from primary tumor cells has become a common method to identify genes critical to the development and progression of cancer. We seek to identify those genetic and epigenetic aberrations that have the most impact on gene function within the tumor. First, we perform a bioinformatic analysis of copy(More)
The ultimate goal of protein structure prediction is to extend our knowledge and understanding of the structures and functions of proteins beyond that which is possible by experiment. Virtually all techniques, including 1D, 2D, and 3D structure prediction, and diverse kinds of function prediction use profiles rather than single sequences as the 'information(More)
In 2010, the World Health Organization reclassified the entity originally described as intraductal oncocytic papillary neoplasm as the 'oncocytic subtype' of intraductal papillary mucinous neoplasm. Although several key molecular alterations of other intraductal papillary mucinous neoplasm subtypes have been discovered, including common mutations in KRAS,(More)
MOTIVATION Microarray expression data reveal functionally associated proteins. However, most proteins that are associated are not actually in direct physical contact. Predicting physical interactions directly from microarrays is both a challenging and important task that we addressed by developing a novel machine learning method optimized for this task. (More)
Bovine liver glutamate dehydrogenase is an allosteric enzyme which is activated by ADP. The affinity label adenosine 5'-O-[S-(4-bromo-2,3-dioxobutyl)thiophosphate] (AMPSBDB), a new ADP analog featuring a reactive group at a position equivalent to that of the pyrophosphate, reacts with this glutamate dehydrogenase to yield enzyme containing about 0.9 mol/mol(More)
SMAC/DIABLO is a mitochondrial proapoptotic protein that is released from mitochondria during apoptosis and counters the inhibitory activities of inhibitor of apoptosis proteins, IAPs. By linkage analysis and candidate screening, we identified a heterozygous SMAC/DIABLO mutation, c.377C>T (p.Ser126Leu, refers to p.Ser71Leu in the mature protein) in a(More)
OBJECTIVE Ovarian cancers are highly heterogeneous and while chemotherapy is the preferred treatment many patients are intrinsically resistant or quickly develop resistance. Furthermore, all tumors that recur ultimately become resistant. Recent evidence suggests that epigenetic deregulation may be a key factor in the onset and maintenance of(More)
The sub-cellular localization of a native protein constitutes one coarse-grained aspect of its function. Transport between compartments is often regulated through short sequence motifs. Here, we analyzed experimentally characterized endoplasmic reticulum (ER)/ Golgi retrieval motifs and investigated the accuracy of homology-transfer. Only the C-terminal ER(More)
