Methuselah-like proteins

The Methuselah-like proteins are a family of G protein-coupled receptors found in insects that play a role in aging and reproduction. Antagonizing these receptors can extend the life span of the animal and make it more resistant to free radicals and starvation, but also reduce reproduction and increase cold sensitivity. The age depends on the action and motor function is unaffected. [2]

Methuselah-like proteins are related to the protein-coupled receptors of the secretin receptor family. [1]
