The main function of the iORpdb module is to demonstrate the spatial structure of iORs predicted by AF2. Visitors can search and download the PDB structure files contained in iORpdb according to the species they are interested in. The 3D structure and related information, including the transmembrane counts of all potential iORs, can be shown on the iORpdb pages for users, allowing them to intuitively check for functional reasonableness. In addition, the iORpdb module provides the Ramachandran function to evaluate the 3D structure of PDB structures contained in iORbase, which can be used to estimate the accuracy of the predicted protein 3D structures.The main function of the iORpdb module is to demonstrate the spatial structure of iORs predicted by AF2.
