Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Transcription factor that specifically binds AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs) (PubMed:25336567). Encodes a nuclear matrix protein that acts in the maintenance of genomic integrity by silencing TEs and repeat-containing genes through epigenetic machinery. Acts as a chromatin remodeling factor that modifies the architecture of FLC and FWA chromatin by modulating both H3 acetylation and methylation leading to the regulation of FLC and FWA expression (PubMed:23394836, PubMed:23836195). Negatively regulates floral repressors including MAF4 and MAF5 (PubMed:23733063). Plays a transcription activation role in anther development. Regulates the expression of arabinogalactan proteins (AGPs) involved in the formation of the nexine layer of the pollen wall (PubMed:25336567, PubMed:24804694). Binds AGP6, AGP11, AGP23 and AGP40 promoters (PubMed:25336567).By similarity5 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.
