Lots of things may be useful, but it depends on the nature of the 
protein and its composition.  No one here is going to be able to tell 
you what to do, nor is that the purpose of this list.  Research what is 
known about your system, think about its architecture and interactions 
within itself.

10 ns is not nearly enough data to conclude anything meaningful.
