DDM1_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: DDM1_ARATH
• UniProt AC: Q9XFH4
• Protein Name: ATP-dependent DNA helicase DDM1
• Gene Name: DDM1
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 764
• Subcellular Localization: Nucleus . Closely associated with pericentric heterochromatin..
• Protein Description: ATP-dependent DNA helicase that plays a role in formation, organization, stability and heritability of heterochromatin and thus regulates several physiological traits. Binds to the nucleosome and promotes chromatin remodeling in an ATP-dependent manner; induces nucleosome repositioning on a short DNA fragment, and, possibly, could be guided to target sites (including silent transposable elements) by small interfering RNAs (siRNAs). Can bind both free and nucleosomal DNA. Required for the heritable maintenance of genome integrity and transcriptional gene silencing (TGS), including homology-dependent gene silencing (HDG silencing), via the maintenance of DNA methylation (mostly on cytosine, in both CpG and CpHpG sites, where H is A, T or C) and of histone methylation (e.g. chromatin methylation). May facilitate localization of MBD proteins at specific nuclear domains. Necessary for the maintenance of the genomic imprint at the MEA locus, especially for the silencing of paternally inherited MEA locus. Plays a major role in the inactivation maintenance of retrotransposons (e.g. Tar17, SINE, LINE, ATLN39, CAC1 (CACTAs), Athila elements, and mutator-like elements MULEs and TIR-MULEs) and the silencing of repeated genes and transgenes (e.g. T-DNA insertions). Required for KYP-dependent histone H3 'Lys-9' (H3K9me) methylation, deacetylation of histone H4 'Lys-16' (H4K16) and MET1-dependent DNA methylation. Involved in the chromatin organization of 5S rRNA genes (localized in the pericentromeric heterochromatin of chromosomes 3, 4, and 5) modifications during heterochromatin establishment. Prevents siRNA accumulation (siRNA are probably involved in epigenetic inheritance and in 5S rRNA genes regulation by silencing). Required during plant organogenesis and development, as well as during seed formation..
