Properties of a Tobacco DNA Methyltransferase, NtMET1 and Its Involvement in Chromatin Movement during Cell Division

Abstract

The results suggest that enzymatic activity of NtMET1 is well adjusted by its own intra/intermolecular interaction and perhaps by interactions with other proteins, one of which was found to be Ran GTPase. Results also revealed that NtMET1 becomes localized to the vicinity of chromatin with the aid of Ran GTPase during cell division, and may play an important role in progress through mitosis independently of methylation activity.
