H3K4me3 is an epigenetic modification to the DNA packaging protein Histone H3 that indicates tri-methylation at the 4th lysine residue of the histone H3 protein and is often involved in the regulation of gene expression. [1]
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 histones can either increase or decrease transcription of genes, depending on which amino acids in the histones are methylated, and how ...
H3K4me1 is a chromatin signature of enhancers, H3K4me2 is highest toward the 5′ end of transcribing genes and H3K4me3 is highly enriched at promoters and in poised genes. H3K27me3 , H4K20me1 and H3K4me1 silence transcription in embryonic fibroblasts, macrophages, and human embryonic stem cells (ESCs).
[citation needed] PAD4 is the deaminase involved in histone modification and converts arginine to citrulline on histones H3 and H4; because arginine methylation on these histones is important for transcriptional activation, citrullination of certain residues can cause the eventual loss of methylation, leading to decreased gene transcription ...

Circadian Rhythm Fasting For Muscle Gain While there’s already an established connection between fasting diets, like CRF, and weight loss, muscle gain is a bit more murky, McDaniel says.
H3K36me3 is an epigenetic modification to the DNA packaging protein Histone H3.It is a mark that indicates the tri-methylation at the 36th lysine residue of the histone H3 protein and often associated with gene bodies.
