Peptides (Epigenetic Regulators) in the Structure of Rodents with a Long and Short Lifespan

Аннотация

We have discovered motives of short-chain epigenetically active peptides in some proteins of long-lived African mole rat Heterocephalus glaber. These epigenetic regulators are located in the protein structure between lysine and arginine residues, thus facilitating their release in limited proteolysis. Some of these epigenetic regulators are not found in the proteins of short-lived species — Norway rat Rattus norvegicus and house mouse Mus musculus.
