Fremont CA – May 21, 2012 -- Proteins undergo post-translational modifications (PTM) as a mechanism to expand the coding capacity of genes.1 PTMs found in histone “tails” (amino termini) such as acetylation, methylation and phosphorylation affect chromatin structure and exquisitely regulate gene expression.2-7
The use of synthetic histone peptides containing PTMs has helped unraveled some of the mysteries of PTMs and their interaction with downstream effectors. For example, the use of 15-20 amino acid long histone peptides containing biotin either on the N or C-terminus used in pull-down assays has advanced the understanding of these epigenetic relationships.8-9
At AnaSpec, EGT Group, we are pleased to be a source of premium quality amino acids, whether Fmoc or Boc protected, for PTM peptide synthesis. In addition to PTM lysines and arginines, Fmoc protected phosphorylated D and L-serines and threonines are also available.
