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.

Molecular chaperone; assists the folding of proteins upon ATP hydrolysis. Known to play a role, in vitro, in the folding of actin and tubulin. Contributes to stem cell maintenance through its impact on transcription factors trafficking through plasmodesmata (PubMed:21868675). Probably involved in refolding translocated, partially unfolded proteins, including viral movement proteins (PubMed:21868675, PubMed:22476462).1 Publication1 Publication

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