Annotation score:5 out of 5

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

Transcription factor that binds to the motif 5'-GTAACNT-3' in the promoter of target genes (e.g. DD11 and DD18) and promotes their expression within synergid cells (e.g. in the filiform apparatus) in ovules (PubMed:16214903, PubMed:17693534, PubMed:18410484, PubMed:17937500). Required for the formation of the filiform apparatus during synergid cell differentiation in the female gametophyte (PubMed:16214903). Involved in pollen tube guidance to the micropyle (PubMed:16214903, PubMed:17937500, PubMed:23093426).5 Publications

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