Figure 1

Profilin transcripts have multiple Mettl3 binding sites. PFN1 mRNA, depicted in cartoon form at the top, has Mettl3 binding sites (AAACC) depicted by black boxes in the 3′UTR and 5′UTR. PFN2 mRNA represented as the transcript in the middle of this figure, has Mettl3 binding sites (AAACA) in the 3′UTR, exon 3, intron 1, and intron 2. PFN2 mRNA has additional binding sites in 3′UTR represented by green box (UGUGGACU). chic (Drosophila profilin), depicted as the bottom cartoon in this figure, has a cluster of METTL3 binding sites (GTTCTTATTTCTCCGCCGCTGACGGTG) in intron 3 represented by red box. This cluster, when run through appropriate algorithms, can generate hairpins for complex recognition.
