Specifically recognizes and binds N6-methyladenosine (m6A)-containing RNAs, and regulates mRNA stability (By similarity). M6A is a modification present at internal sites of mRNAs and some non-coding RNAs and plays a role in mRNA stability and processing (By similarity). Interacts (via C-terminus) with CIPK1. Localizes predominantly in the nucleus. Expressed in root apex, shoot apex, lateral root primordia, stamens, carpels and trichomes.
