<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Receptor that may play a role in the perception of bitterness and is gustducin-linked. May play a role in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5.

Miscellaneous

Most taste cells may be activated by a limited number of bitter compounds; individual taste cells can discriminate among bitter stimuli.Curated

<p>The checksum is a form of redundancy check that is calculated from the sequence.
