Webb7 aug. 2014 · To further investigate the molecular mechanism of the self-reinforcing feedback loop between DNA and histone methylation in plants, we carried out structural and functional studies, which revealed a distinct mechanism by which KYP specifically recognizes mCHH and mCHG DNA, as well as how KYP recognizes its target histone …
Effect of SMYD3 on biological behavior and H3K4 methylation in …
The fundamental unit of chromatin, called a nucleosome, contains DNA wound around a protein octamer. This octamer consists of two copies each of four histone proteins: H2A, H2B, H3, and H4. Each one of these proteins has a tail extension, and these tails are the targets of nucleosome modification by … Visa mer Histone methylation is a process by which methyl groups are transferred to amino acids of histone proteins that make up nucleosomes, which the DNA double helix wraps around to form chromosomes. Methylation of … Visa mer The genome is tightly condensed into chromatin, which needs to be loosened for transcription to occur. In order to halt the transcription of a … Visa mer In female organisms, a sperm containing an X chromosome fertilizes the egg, giving the embryo two copies of the X chromosome. Females, however, do not initially require both copies of the X chromosome as it would only double the amount of protein … Visa mer In one-carbon metabolism, the amino acids glycine and serine are converted via the folate and methionine cycles to nucleotide precursors and SAM. Multiple nutrients fuel one … Visa mer Histone methylation, as a mechanism for modifying chromatin structure is associated with stimulation of neural pathways known to be important for formation of long-term memories and … Visa mer Modifications made on the histone have an effect on the genes that are expressed in a cell and this is the case when methyls are added to the histone residues by the histone … Visa mer Due to the fact that histone methylation regulates much of what genes become transcribed, even slight changes to the methylation patterns can have dire effects on the organism. … Visa mer WebbAs a PhD. researcher I identified the CRL4 E3 ligase components that regulates DNA methylation and Histone modifications in Neurospora crassa.
