From Proteopedia

What do you do when the pdb code only provides the monomeric form of a protein, but you can see a dimeric, trimeric or other higher-order structure on the PBD site?

Well, first you need to determine if that multimeric structure is just an artistic rendering of the molecule or if there is a file containing the 3-D structure.

For example, if you are interested in the Potassium Channel KcsA-Fab complex, you might include a structure window box on your Proteopedia page that displays 1k4c. This file will display the protein in a monomeric state, as shown here.

However, if you go tothe PDB and search for 1k4c, you'll be greeted with a tetrameric view of the same protein.
