Welcome to the GPCR-OKB

The GPCR-OKB is an information management system that allows browsing, visualization, and structured querying of computational and experimental information about G Protein-Coupled Receptor (GPCR) oligomerization, thus supporting productive and quantitative communication between computational and experimental scientists working in the field.

Although many biochemical and biophysical data are consistent with the ability of monomeric receptors to activate heterotrimeric G-proteins, more and more experimental evidence indicates that GPCRs can self-associate and/or interact with other GPCRs. For simplicity, GPCR-OKB will refer to GPCR oligomers, although the majority of the reported studies do not discriminate between dimers, tetramers, or higher-order oligomers.
