Gene

hel308

Status
Reviewed-Annotation score:

Annotation score:4 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.

DNA-dependent ATPase and 3'-5' DNA helicase that may be involved in repair of stalled replication forks. Helicase with 3'-to 5'- polarity; able to unwind over 100 bp of DNA at 50 degrees Celsius. Unwinds forked DNA, preferentially on lagging strand forks; has weaker activity on Holliday junctions. Displaces the invading strand in DNA D-loops. Unwinds short oligonucleotides from dsDNA with 3'- but not blunt ends or 5'-ssDNA tails in an ATP-dependent manner. ATPase activity is stimulated by ssDNA but not dsDNA, protein binds ssDNA, dsDNA with 5'- or 3'-overhangs but not blunt ended dsDNA and replication forks. Replication forks bind both this protein and RPA. RPA does not stimulate the helicase activity of this protein.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i90BEE6110C4133F3
