## High Level, Long Term Vision + Identify Structure/Function Relationships - Determine active sites and "mates" on unknown structures. Find ligand binding sites and potential protein/protein interactions. - Determine how changes to structure might induce changes to function. (e.g. find hotspots for mutation) - Determine the geometric, kinematic, and dynamic mechanisms for chemical processes. ## Ideas on Achieving these goals + Determination of "features" for performing matching and categorization. Various tasks on the top list would be addressed this way (active site function determination, hotspot finding, ...) - features that categorize geometry / spatial chemistry, not necessarily underlying sequence - features that are "stable" across the diversity of similar functions and motions + Applying good "informatics" techniques to these "features" - bag of feature methods - flexible templates + Simplified representations of geometric complexity and motions + "Molecular Morphing" as a useful tool - especially when things can be "driven" and stay "feasible" - drive molecules between different configurations to perform comparisons - "pry open" closed things, "pull closed" open things to get ideas of what they look like in different states ## Core technical components + Good "kinematic simulation" of molecules to move between different states, or make two dissimilar things similar enough to look at. - elastic normal modes + direction projection, differential disallowment, re-rigidification (FRODA-style) - differential disallowment advantages: - can do stabilization - can be "driven" towards goals more easily - can be tuned (but needs to be tuned) - can deal with non-overlap constraints - can use hierarchical methods (for both collisions and for movement) + Geometric feature points - Finite things to try to match / accumulate / ... - Stability across diversity - independent of representation ## Visualization tasks + Be able to compare interfaces (across different molecules, same molecule in different states, ...) - determine stability of properties of interest + Look at motions - understand what's the same and different
