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.

Miscellaneous

Duplicated gene. CDK11A and CDK11B encode almost identical protein kinases of 110 kDa that contain at their C-termini the open reading frame of a smaller 58 kDa isoform which is expressed following IRES-mediated alternative initiation of translation.

Caution

During FAS- or TNF-induced apoptosis, isoform SV9 is cleaved by caspases to produce p110C, a fragment that contains the C-terminal kinase domain.
Phosphorylation at Ser-115 creates a binding site for 14-3-3 proteins. p110C can be autophosphorylated.2 Publications

Cleaved isoform SV9 (p110C) binds to the serine/threonine kinase PAK1 and RANBP9. p110C interacts with RNPS1. Isoform 7, but not isoform SV9, nor its cleavage product p110C, interacts with CCND3.

Interacts with CCNL1 and CCNL2. Forms complexes with pre-mRNA-splicing factors, including at least SRSF1, SRSF2 AND SRSF7/SLU7.

Interacts with isoform 5 of MYO18A (PubMed:25965346).

<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:i8CCB0E688E66DF47

<p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P21127
