The Protein Feature View provides a graphical summary of a full-length protein sequence from UniProtKB and how it relates to PDB entries. It also loads annotations from external databases such as Pfam, Phosphosite, domain annotations from SCOP and SCOPe, or regions for which homology models are available from the Protein Model Portal. There are also tracks of annotations available that visualize predicted regions of protein disorder (computed with JRONN) and hydrophobic regions, as computed using a sliding window approach. Predicted disordered and hydrophobic regions are in red, ordered and hydrophilic regions are in blue. For human proteins, that can be mapped to the human genome, a track describes the projection of the protein structure onto the genome.
By default representative PDB entries are being displayed that give an overview for which regions of the UniProtKB sequence PDB entries are available. The view can be expanded to show all available PDB entries (which can be many in some cases) by pressing the "+" icon or by selecting the "Extended" menu option.

The header section of the Protein Feature View shows information about the Function, Catalytic Activity and subunit structure (if available) from UniProtKB. It also has an option to select Protein Feature Views from related organisms with the same gene name.
The Action button has an option to map sequence motifs in the Protein Feature View as shown below.
