What Cellular Components are included here?

Vocabulary terms describing cellular component locations, developed by the Gene Ontology Consortium (GO), are used to organize PDB structures in this browser. Cellular Components are mapped to PDB entities based on their UniProt sequences and using the Structure integration with function, taxonomy and sequence (SIFTS) project. Cellular components are listed in this browse tree only if they have a protein in a PDB structure mapped to it.

Why browse by Cellular Component?

Browsing through this tree can help identify protein entities that are localized in a specific cellular location/compartment. You can examine the structures of protein entities grouped together to see if there are any common features or trends in these proteins.

How to use the Cellular Component Browser ?

The Cellular Component browser allows users to type in a cell component name, select a GO term, or enter a 7 digit GO ID in the search box to identify the corresponding PDB entities.

After locating the cellular component of interest in the browser, users can view the number of polymers in this group. Clicking on the numbers listed next to the component name will launch a search for all polymer entities in the PDB that are associated with it.

Example

Browse the PDB archive for entities that are located in the lysosome as follows:

• Type the name of a cellular component of interest in the search box on the page e.g., "lysosome" and select from the options" lysosome (GO ID:5764)" OR
• Type the 7 digit GO ID:0005764. If you begin typing the ID 5764, in the search box on the top of the page, autocomplete suggestions will appear, from which you can select the appropriate options to search through the browser tree.
