 The first step is to go to the CATH home page (http://www.cathdb.info/) and just take a quick look. To the right hand side you can find a column of boxes with links to new developments in CATH. Other links to useful information (references, search tools) can be found in the main part of page, as well as in the footer, which is found at the bottom of every page. Up in the top right you can find links to the key functions of the web site and the ‘Quick Search’ box. This is where we are going to start. Enter the PDB code 1gcq into this box and hit the button (or the ‘Enter’ key). The first step is to go to the CATH home page (http://www.cathdb.info/) and just take a quick look.

 In a CATH results page all the records that may correspond to the query term are returned. The possible return types are ‘Domain’, ‘Chain’, ‘PDB’ and ‘Node’. Node corresponds to a node in the CATH structural hierarchy, i.e. a superfamily. It is worth noting that a CATH domain code is an extension of the PDB Chain identifier (i.e. 1gcqA00 is a domain in chain 1gcqA, which is found in record 1gcq). In a CATH results page all the records that may correspond to the query term are returned.

 In the sequence features tab clicking for VAV1 click on the link  'Click here for Proteins with similar CATH arrangements' and this will retrieve other proteins with a similar domain organisation. Also on this page is a summary of GO annotations and associated evidences for all proteins with this domain organisation. You can then retrieve the sequences from the organism of interest for example for homo sapiens.  In the sequence features tab clicking for VAV1 click on the link  'Click here for Proteins with similar CATH arrangements' and this will retrieve other proteins with a similar domain organisation.
