Histone methyltransferase that specifically di- and trimethylates 'Lys-20' of histone H4 (H4K20me2/me3) (PubMed:22393255, PubMed:23028348). H4 'Lys-20' trimethylation represents a specific tag for epigenetic transcriptional repression (By similarity). Contributes to dosage compensation of X chromosome-relative to autosome-linked gene expression, possibly by converting H4K20me1 to H4K20m2/me3 on autosomes (PubMed:26641248, PubMed:23028348, PubMed:22393255). Involved in the regulation of growth and body fat metabolism downstream of the TOR complex 2 pathway (PubMed:23884442).By similarity4 Publications

Mutant animals exhibit a lack of di- and trimethylation (H4K20me2/me3) and an increase of monomethylation of 'Lys-20' (H4K20me1) of histone H4 on autosomes, leading to equal H4K20me1 levels on autosomes relative to X chromosomes (PubMed:22393255, PubMed:23028348, PubMed:26641248). Decreased expression of autosomal genes (PubMed:26641248). Increase in 'Lys-16' acetylation of histone H4 (H4K16ac) on hermaphrodite X chromosomes (PubMed:22393255). Increase in binding of the RNA Pol II large subunit ama-1 on X chromosome gene promoters relative to autosomes (PubMed:26641248). In a dpy-21 mutant background, RNAi-mediated knockdown leads to embryonic lethality (PubMed:23028348). In the TOR complex 2 mutant background rict-1, suppresses the growth delay and elevated body fat index (PubMed:23884442).4 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.
