amberly, thank you for your reply. You have a good command of English.
Domain means 结构域 in Chinese, which is commponent of transmembrane channel structure as to ion channel protein.
The protein I am concerned with is one of sodium channel ones, surely belonging to ion channel family. And its function and crystal strunture are all well known, not needed to make prediction any more.
Topology of proteins can tell us their spatial structures, but can't supply the information on its transmembrane configuration with respect to channel forming.
Thanks for telling me websites cuturl('www.pdb.org') and cuturl('www.mpdb.ul.ie.') I used them to perform my searching. However, cuturl('www.pdb.org') gives only result of topology of protein, while cuturl('www.mpdb.ul.ie') gives no records.
The picture I pasted above was captured from the protein's whole illustration, i.e. it's only a part of it, much more complicated. Therefor, Powerpoint of MS Office and the like are not capable of performing the task.
More answers are expected to solute the problem.
