Alternative splicing (AS) generates vast transcriptomic and proteomic complexity. However, which of the myriad of detected AS events provide important biological functions is not well understood. Here, we define the largest program of functionally coordinated, neural-regulated AS described to date in mammals. Relative to all other types of AS within this(More)
Metal ions are crucial for protein function. They participate in enzyme catalysis, play regulatory roles, and help maintain protein structure. Current tools for predicting metal-protein interactions are based on proteins crystallized with their metal ions present (holo forms). However, a majority of resolved structures are free of metal ions (apo forms).(More)
We describe a suite of SPACE tools for analysis and prediction of structures of biomolecules and their complexes. LPC/CSU software provides a common definition of inter-atomic contacts and complementarity of contacting surfaces to analyze protein structure and complexes. In the current version of LPC/CSU, analyses of water molecules and nucleic acids have(More)
The limited size of the germline antibody repertoire has to recognize a far larger number of potential antigens. The ability of a single antibody to bind multiple ligands due to conformational flexibility in the antigen-binding site can significantly enlarge the repertoire. Among the six complementarity determining regions (CDRs) that generally comprise the(More)
Protein metal binding sites in the pre-bound (apo) state, and their rearrangements upon metal binding were not analyzed previously at a database scale. Such a study may provide valuable information for metal binding site prediction and design. A high resolution, nonredundant dataset of 210 metal binding sites was created, containing all available(More)
Analysis of the spatial arrangement of protein and water atoms that form polar interactions with ribose has been performed for a structurally non-redundant dataset of ATP, ADP and FAD-protein complexes. The 26 ligand-protein structures were separated into two groups corresponding to the most populated furanose ring conformations (N and S-domains). Four(More)
Computational protein design methods can complement experimental screening and selection techniques by predicting libraries of low-energy sequences compatible with a desired structure and function. Incorporating backbone flexibility in computational design allows conformational adjustments that should broaden the range of predicted low-energy sequences.(More)
