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.

Core histone-binding subunit that may target chromatin assembly factors, chromatin remodeling factors and histone deacetylases to their histone substrates in a manner that is regulated by nucleosomal DNA. Component of several complexes which regulate chromatin metabolism. These include the chromatin assembly factor 1 (CAF-1) complex, which is required for chromatin assembly following DNA replication and DNA repair, and the fertilization independent seed (FIS) complex, a polycomb group protein complex which is required to maintain the transcriptionally repressive state of homeotic genes throughout development. Required for several aspects of plant development including normal leaf expansion, correct development of flowers, normal endosperm development, repression of parthenogenetic seed development and repression of floral homeotic genes in leaf tissue. Also required for the recruitment of chromosomal DNA into heterochromatic chromocenters. Also involved in regulation of imprinted genes. Acts together with RBR1 to repress the expression of MET1 during female gametogenesis. This in turn activates expression of the imprinted genes FIS2 and FWA.

<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.
