How do I search for a protein sequence?
To show the Find controls, click Edit → Find.
The Find controls will appear near the bottom of the window.
A protein sequence search is restricted to visible translations, which are typically present in translated features. If you also wish to show full-sequence translations, click the Show Translations button.
Choose Find protein sequence:.
To allow any amino acids at a specific position, use X.
To exclude amino acids at a particular position, use an exclamation point in front of the forbidden amino acids. For example, !P means not P.
Alternatively, enclose the excluded amino acids in parentheses. For example, !(ST) means not S or T.
To search for a degenerate amino acid, enclose the entire query in quotes. For example, a search for X will find all matches to any letter (A-Z), but a search for "X" will find only bases actually represented as X.
The other degenerate amino acids are B (matching either D or N) and Z (matching either E or Q).
To review or reuse recent searches, click the arrow button on the search box.
In Map view, a matching protein sequence will be highlighted in blue.
In Sequence view, a matching protein sequence will be highlighted in blue.
To view examples of protein searches, click Help → Search Tips, then scroll down.
