Hi Chen, In this case, it seems that linker region is of great importance for the proper folding of the two linked domains. I have not much experience in linker region design, generally use (GS)5-10 times. However it depends on individual case. Anyone who has successful experience in linker region design might share your success with others. Thanks a lot.
