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>

Endonuclease that cooperates with the MRX complex in processing meiotic and mitotic double-strand breaks by allowing the endonucleolytic removal of SPO11 from the break sites and ensuring both resection and intrachromosomal association of the broken ends. Required for proper recovery from checkpoint-mediated cell cycle arrest after DNA damage. MRX complex and SAE2 remove a small oligonucleotide(s) from the DNA ends to form an early intermediate which is rapidly processed by EXO1 and/or SGS1 to generate extensive tracts of single-stranded DNA that serve as substrate for RAD51. Plays a transitional role in the dissociation of MRE11 from, and the recruitment of RAD52 to, repair foci. Ensures that both ends of a DSB participate in a recombination event and impairs the formation of palindromic structures in the genome. With TEL1, promotes microhomology-mediated end joining (MMEJ) but inhibits non-homologous end joining (NHEJ), likely by regulating MRE11-dependent ssDNA accumulation at DNA break. SAE2 and MRX are particularly important for removal of hairpins, bulky adducts and other irregular end structures. Facilitates telomere length reequilibration and subsequent checkpoint switch off. Involved in homing efficiency of VMA1 intein VDE and in repair of transposon excision sites.25 Publications

Phosphorylated forms accumulate periodically during the unperturbed cell cycle and in response to DNA damage in G2. Phosphorylated by MEC1 and TEL1. Mutagenesis experiments showed that several of the 5 residues located in canonical (S/T)Q motifs, which are favored for phosphorylation by ATM/ATR kinases (Ser-73, Thr-90, Ser-249, Thr-279 and Ser-289) may be phosphorylated. Phosphorylated at Ser-267 by CDC28 which is required to initiate meiotic DSB resection by allowing SPO11 removal from DSB ends.6 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.
