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.

Cyclin subunit of the CTDK-I complex, which hyperphosphorylates the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit. CTDK-I phosphorylates 'Ser-5' if the CTD substrate is not phosphorylated at 'Ser-5', but will phosphorylate 'Ser-2' of a CTD substrate if 'Ser-5' is already phosphorylated. CTDK-I is also more reactive toward substrates that are prephosphorylated at 'Ser-2' or 'Ser-5' compared with an unphosphorylated CTD substrate, therefore efficiently creating doubly phosphorylated CTD repeats. Involved in RNA polymerase II transcriptional elongation, and as part of the CTDK-I complex, pre-mRNA 3'-end processing and SET2 mediated H3K36 methylation. Together with CTK3, required for CTK1 CTD kinase activation. Required for DNA damage induced transcription. Involved in the adaptation to alternative carbon sources, including galactose, glycerol and ethanol, but not raffinose. Required for the integrity of the rDNA locus.6 Publications

Null mutants are viable, but grow more slowly than wild-type cells at 30 degrees Celsius. They are cold-sensitive, failing to grow at 12 degrees Celsius. They display flocculent growth in liquid media and they show abnormal cell morphologies, for example, a significant fraction of the cells are greatly enlarged. Deletion mutant is sensitive to the DNA synthesis inhibitor hydroxyurea (HU) and UV irradiation.2 Publications

<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:i7C18FA672778D8FD
