For the T-model, 1708 GPCR-target (from 758 GPCR-agonists and 950 GPCR-antagonists) and 2206 GPCR-nontarget were used in the training dataset. WebGPCRs are composed of various independent folding units: receptor fragments (e.g. rhodopsin, M3 muscarinic) can assemble to form functional receptors (e.g. TM1-5 and TM6-7). Consistent with idea that TM helices are tightly packed in ring like structure in membrane. 9. GPCRs function as monomers (dogma); but increasing evidence for
