Functional Site Analysis in Proteins of G Protein Signaling Pathways Using Fuzzy Evolutionary Trace Method

GPCRs are physiologically significant receptors linked to numerous diseases including cardiovascular disease, mental illness, and cancer. Inhibiting the interaction between a GPCR and its G-protein blocks the ability of the receptor to initiate a signal in a cell. G protein active sites control nearly all G protein functions and determine the interactions upon which G protein signaling pathways are built. Characterization of the active sites in G protein or GPCRs would therefore lead to new methods of controlling G proteins and ultimately controlling cells. This paper use fuzzy evolutionary trace method to analyze the binding sites of G protein and finally give an example
