One promising potential application of such mathematical models is the study of how disease-causing mutations develop a mechanistic mathematical model of a G-protein coupled receptor signaling network that is mutated Modeling the two major, mutually-exclusive, oncogenic mutations (Gαq/11 and CysLT2R) revealed the potential This led us to hypothesize that CYSLTR2 mutations in UM must co-occur with other mutations to activate FAK/YAP/TAZ signaling, and our bioinformatic analysis uncovers a role for co-occurring mutations involving
