Histone H4R3Me2s (1-21)-GGK-biotin (trifluoroacetate salt)

Histone H4R3Me2s (1-21)-GGK-biotin is a peptide fragment of histone H4 that corresponds to amino acid residues 2-22 of the human H4 sequence. It is symmetrically dimethylated at arginine 3 and biotinylated via a C-terminal GGK linker. Symmetric dimethylation of histone 4 at arginine 3 is associated with transcriptional repression. It can recruit the DNA methyltransferase DNMT3a, leading to DNA methylation and further transcriptional repression. Histone H4R3Me2s (1-21)-GGK-biotin has been used as a substrate for the qualitative measurement of jumonji domain containing 1B (JMJD1B) arginine demethylase activity and in dot blot assays to verify antibody specificity.Formal Name: N2-(N2-acetyl-L-serylglycyl-Nomega,Nomega'-dimethyl-L-arginylglycyl-L-lysylglycylglycyl-L-lysylglycyl-L-leucylglycyl-L-lysylglycylglycyl-L-alanyl-L-lysyl-L-arginyl-L-histidyl-L-arginyl-L-lysyl-L-valylglycylglycyl)-N6-(5-((3aS,4S,6aR)-2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanoyl)-L-lysine, trifluoroacetate salt.
