Area of Research


Dr. Daisuke Kihara
Principal Investigator

Our research interests lie in the area of bioinformatics. We employ computational methods to elucidate intertwined relationships between protein/gene sequences, structure, function, interactions, genome, and pathways. The ultimate goal of our research projects is to obtain new, comprehensive understanding of how structures and functions are coded in molecular sequences and how functions of molecules are orchestrated in a cell.

Specifically, we develop and apply novel computational methods for...

  • Predicting protein structure from sequence
  • Predicting protein function from sequence and structure
  • Predicting protein-protein and protein-ligand interactions
  • Predicting functional sites in sequences
  • Genome-scale function and structure annotation
  • Analyzing functional units in networks

Research Highlights


3D-SURFER 2.0 is a web platform for real-time protein surface comparison of a given protein structure against the entire PDB using 3D Zernike descriptors. It can compare the protein surface of a single chain, domain, or complex against databases of protein chains, domains, complexes, or a combination of all three, in the latest PDB. The databases are weekly updated. Visit the server or read the paper.
The protein docking suite developed includes programs to perform protein-protein docking prediction, multiple protein docking, as well as protein docking prediction using predicted protein-protein interfaces. The Linux binaries can be downloaded here
EESG is a sequence similarity-based protein function prediction server. It employ PSI-BLAST iteratively and essentially selects GO term annotations that appear consistently in the searches. Visit the server to submit a sequence or read the paper. ESG was among top in the 1st CAFA function prediction assessment.
PFP is a sequence similarity-based protein function prediction server designed to predict GO annotations for a query sequence beyond what can be found by conventional database search such as BLAST.It takes into account weakly similar sequences as well as GO term associations observed in known annotations.
Visit the server to submit a sequence or read the paper. PFP had the highest total score in a function prediciton contest held at AFP-SIG'05 (ISMB2005), and also was the best in the function prediciton category at CASP7.
