Identification and expression of adenosine deaminases acting on tRNA (ADAT) during early tail regeneration of the earthworm.

Our results demonstrate that Ean-ADAT belongs to a class of ADAT1s and support the hypothesis of a common evolutionary origin for ADARs and ADATs. The temporal expression of Ean-ADAT could suggest that its activity is unrelated to the molecular mechanisms of dedifferentiation.
