Note:

• For each entry, the GPCR-HGmod data include top-five full-length models, LOMETS template and alignments, secondary structure prediction, solvent accessibility prediction, and residue-specific error and B-factor predictions.
• The GPCR-I-TASSER models have generally higher resolution in the transmembrane regions; users should bear cautions on using the loop and tail regions of the models which have usually a relatively lower resolution. Users are encouraged to check the attached residue-specific quality (ResQ) prediction to assess the local structure errors.
• All the models were constructed from the GPCR sequence alone. An attachment of addition ligand molecules may change the conformation of the structures.
• Experimentally solved GPCR structures can be found at GPCR-EXP Database.
