CRT home > Arcadia: Query for wildtype and mutant proteins

Query for wildtype and mutant proteins:

This is the main entry page into Arcadia. It allows the user to query the database for both mutants and wildtype proteins which are stored there. There are a number of different pulldown menus, which can allow the user to refine their query to be able to find the entry of interest more quickly and efficiently.

Clicking the Search button will retrieve a list of matching entries, which can then be viewed in more detail.

There are three main ways of refining your query: keyword in a field, by organism, and whether you want a mutant or a wildtype protein.


[ The wildtype/mutant protein pulldown menu ]

You can choose to retrieve only wildtype proteins matching your query, only mutant proteins, or both.


[ The organism pulldown menu ]

You can refine your search so that only wildtype and/or mutant proteins (depending on your selection from the pulldown menu desribed above) from this organism are returned if they match your query.


[ The field pulldown menu ]

  1. Keyword in protein name [name]
    The names of all the wildtype proteins in the database are searched to see if they match the keyword given. If the keyword box is left blank, all wildtype and/or mutant proteins are returned.


  2. Keyword in family name [family]
    The family names of all the wildtype proteins in the database are searched to see if they match the keyword given.


  3. Keyword in description [desc]
    The user-given descriptions of all mutant proteins are searched for a match to the keyword given. If the user has chosen to retrieve wildtype proteins, the wildtype proteins from which the mutant proteins that match the description keyword are derived are returned.


  4. Accession code [ac]
    The accession codes from external databases (such as Swissprot or Genbank) which are associated with the wildtype proteins in Arcadia are searched.


  5. Mutant ID [mid]
    The Arcadia mutant IDs are searched. IDs can be entered either as 'dlm1000' or as the number alone '1000'. When using this option, the organism option is ignored. Again, if the user has chosen to retrieve wildtype proteins only, the wildtype protein associated with the mutant which has this ID is returned.


  6. Submitter [submitter]
    The submitter field is searched. The name of the submitter must be entered exactly as it appears.


  7. Position [position]
    There are three ways of searching using the position option: by absolute position (e.g., 167), generic position, (e.g., 3.50), or by whole transmembrane domain (e.g., TM6).


  8. Advanced
    This option allows you to use a combination of the options above in one query text field, e.g., dopamine[name] transporter[name] 3.50[position] (with no spaces between the keyword and the option). The relevant terms to put in square brackets are given after each field in the above list.

[ Sorting the results ]

The sort pulldown menu allows the user to sort the resulting entries. This is especially useful when there are many entries returned. The default method of listing entries is by their Arcadia ID. Entries can also be sorted by protein name (alphabetically), family name (alphabetically), organism (alphabetically, by Latin name), submitter (alphabetically), mutation (absolute position) and journal (first author name, journal name, and year). Sorting by mutation and journal is only effective for mutant proteins.
