Bioinformatics research areas

• Transcription factor and RNA based gene regulation

– Finding regulatory motifs in co-regulated genes

– Comparing regulatory regions

• Structure prediction and modelling of protein structures

Automatic ligand docking

Potential ligand binding sites

• Part of FUGE Bioinformatics platform

12

miRNA gene and target prediction

• Ongoing research activity

– FUGE project with University of Bergen, using zebrafish to verify prediction of regulatory features (promoters, enhancers, miRNA)

• FUGE application: “The roles of microRNAs and transcription factors in gene regulation and tissue specific expression”

– Includes cell cycle regulation, international collaboration

13

Composite motif discovery

• Find motifs (binding sites) that tend to occur together

• Use general “motif generators” for input

– MEME, Pratt, Teiresias

• Do exhaustive search with efficient search tree pruning for motif combinations with flexible distance and N-of-M matching

Contributions

• Literature scanning, manual curation

– Partly linked to FUGE technology platform

• Experimental test bench, feedback on usage

– Linked to projects on gene regulation

• (Text mining on protein – protein interactions)

• (Ontology data linked to e.g. microarray data)

– (Medical ontologies with versioning)
