Predicted 3D structure

[Dr. D.J. Carucci]

Hi:

I have cloned a new molecule that is structurally related to G-protein
receptors.  I would like to model the 3D structure of this new protein
based on the 3D structure of other G-protein receptor molecules -
to date bacteriorhodopsin.  What computer programs are available to help
me?  I understand there is a program which "threads" a new protein 
primary structure through the 3D structure of another - It was in Science
I believe.  

Thanks

Dan
