MeK is a conserved post-translational modification and is an important biochemical process for many protein-protein interactions. It is found in calmodulin, cytochrome C, chromosomal proteins, histones, non-histones, and neural storage body proteins, as well as others. Data has suggested that methylation of lysine plays a role in gene silencing.
This material consists of BSA containing methylated lysine residues (MeK). It has been reported that at a concentration of 50 åµg/ml this protein can compete with signal from other proteins containing methylated lysines. No inhibition occurs in the presence of 3% BSA.
