Efficient Algorithms for
Detecting Signaling Pathways in Protein Interaction
Networks
My talk will cover a new, efficient method of locating signaling
pathways in
protein-protein interaction networks that was recently presented at
RECOMB
2005. In particular, we have made biologically motivated modifications
and
extensions to classical graph algorithms for path finding. These
changes,
combined with previous work on protein-protein interaction scoring
(turning
experimental data into a probability of interaction), form the core of
our
work. In addition to this theory and design, I will discuss the results
of
running our implementation on the interaction network of yeast -
touching
on runtime, statistical validation, known path recovery, and
implementation
details. I'll close with where our research has progressed since our
RECOMB
submission.
