Specifically recognizes and binds N6-methyladenosine (m6A)-containing RNAs, and regulates mRNA stability (Probable) (PubMed:29716990, PubMed:29618631). M6A is a modification present at internal sites of mRNAs and some non-coding RNAs and plays a role in mRNA stability and processing (Probable) (PubMed:29716990, PubMed:29618631). Binds preferentially in the 3'UTRs of target genes (PubMed:29716990). May play dual roles in regulating 3'UTR processing in the nucleus and facilitating mRNA stability in the cytoplasm (PubMed:29716990). Required for the correct timing of leaf formation and normal leaf morphology (PubMed:29643069). Functions redundantly with ECT3 (PubMed:29643069). Required for proper trichome branching and morphology (PubMed:29643069, PubMed:29716990, PubMed:29618631). Controls trichome morphology by binding transcripts related to trichome morphogenesis and affecting their stability (PubMed:29716990, PubMed:29618631). Interacts (via C-terminus) with CIPK1. Localizes to cytoplasmic foci upon drought stress (PubMed:29643069). Relocates to cytoplasmic stress granules upon heat stress (PubMed:29618631). Expressed in the shoot apex, at the sites of leaf formation, and in emerging leaves (PubMed:29643069). Highly expressed in rapidly developing tissues (PubMed:29716990). Aberrant trichome branching with an increase in number of spikes (PubMed:29643069, PubMed:29716990). The double mutant plants ect2 and ect3 exhibit delayed timing of leaf formation and altered leaf morphology (PubMed:29643069). Sequencing errors.
