A20/AN1 zinc-finger domain-containing proteins in plants and animals represent common elements in stress response
- First Online:
A20/AN1 zinc-finger domain-containing proteins are well characterized in animals, and their role in regulating the immune response is established. Recently, such A20/AN1 zinc-finger proteins have been reported from plants. These plant proteins are involved in stress response, but their exact molecular mechanism of action is yet to be deciphered. Sequence information available in public databases has been used to conduct a survey of A20/AN1 zinc-finger proteins across diverse organisms with a special emphasis on plants. Domain analysis provides some interesting insights into their biological function, the most important being that A20/AN1 zinc-finger proteins could represent common elements of stress response in plants and animals.
