Hi Jason,
I do understand what you are saying but there is one more of difficulty
that my protein of interest is a 6-transmembrane protein and its structure
is not known at all. So, an explicit membrane environment could be
necessary for my protein of interest but not essentially for the GPI-anchor
proteins. This problem therefore looks more challenging and I am not sure
how far I can go with this.
Thank you for your comments and suggestions,
Aditya
