Insights into unbound–bound states of GPR142 receptor in a membrane-aqueous system using molecular dynamics simulations Aman Chandra Kaushik Shakti Sahi 10.6084/m9.figshare.5135536.v1 https://tandf.figshare.com/articles/dataset/Insights_into_unbound_bound_states_of_GPR142_receptor_in_a_membrane-aqueous_system_using_molecular_dynamics_simulations/5135536 <p>G protein coupled receptors (GPCRs) are source machinery in signal transduction pathways and being one of the major therapeutic targets play a significant in drug discovery. GPR142, an orphan GPCR, has been implicated in the regulation of insulin, thereby having a crucial role in Type II diabetes management. Deciphering of the structures of orphan, GPCRs (O-GPCRs) offer better prospects for advancements in research in ion translocation and transduction of extracellular signals. As the crystallographic structure of GPR142 is not available in PDB, therefore, threading and <i>ab initio</i>-based approaches were used for 3D modeling of GPR142. Molecular dynamic simulations (900 ns) were performed on the 3D model of GPR142 and complexes of GPR142 with top five hits, obtained through virtual screening, embedded in lipid bilayer with aqueous system using OPLS force field. Compound 1, 3, and 4 may act as scaffolds for designing potential lead agonists for GPR142. The finding of GPR142 MD simulation study provides more comprehensive representation of the functional properties. The concern for Type II diabetes is increasing worldwide and successful treatment of this disease demands novel drugs with better efficacy.</p> 2017-06-22 13:41:57 GPCR GPR142 molecular modeling MD simulation MM-GBSA
