Temporins are a family of peptides isolated originally from the skin secretion of the European red frog, Rana temporaria.
[1] Peptides belonging to the temporin family have been isolated also from closely related North American frogs, such as Rana sphenocephala.
It was soon discovered that other species of frog also possess temporal, resulting in the discovery of more than 150 peptides from the temporin family.
[3] Temporins are a family of antimicrobial peptides (AMPs), which are highly targetable toward Gram-positive bacteria, allowing it to penetrate the cell wall and damage the inner membrane of the bacteria.
These proteins are also capable of killing specific cancer cells when they are locally administered to a tumor, making it a good anticancer drug.
