Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Developmental protein involved in oogenesis (PubMed:16616913).

Required for germline maintenance, stability of mitotic spindles, localization of patterning determinants, oocyte growth and fusome biogenesis in males and females (PubMed:16616913).

Also required for dorso-ventral and antero-posterior patterning of oocyte and eggshell (PubMed:16616913).

May be involved in microtubule function during oogenesis (PubMed:16616913).

Part of a rhi-dependent transcription machinery that enables the generation of piRNA precursors from heterochromatin while maintaining the suppression of transposon-encoded promoters and enhancers (PubMed:28847004).

Component of the RDC complex (rhi, del and cuff) which binds to repressive H3K9me3 marks in the piRNA clusters (PubMed:28847004).

RDC promotes the bidirectional transcription of piRNA clusters at these sites by interacting with Moonshiner which forms a complex with the transcription initiation factors TfIIA-S and Trf2 (PubMed:28847004).

This mechanism allows transcription to occur in piRNA clusters despite the lack of proper promoter elements and in the presence of the repressive H3K9me3 mark (PubMed:28847004).

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