We used for comparative structure modeling TRPA1 (pdb entry code 3J9P) as template for S1 and S3-S5, TRPV1 (pdb entry code 3J5Q) for S5-S6, and the TRPV2 (pdb entry code 5AN8) fitted best for S2-S3 to obtain an initial model. The soluble domain was build based on pdbID: 5K47. But we had no search model for molecular replacement. Although we had a good idea what the architecture would be like, we build the model de novo with COOT.
