Sequence alignment of a portion of MTA1/2 from a range of eukaryotes. The alignment highlights the high conservation of the first of the RBBP‐binding motifs across a wide range of species, including human (HsMTA1—UniprotID: Q13330, HsMTA2—O94776), Mus musculus (MmMTA1—Q8K4B0), Struthio camelus australis (ScaMTA1—A0A093HEK0), Callorhinchus milii (CmMTA1—V9KH55), Danio rerio (DrMTA3—E7EY65), Drosophila melanogaster (DmMTA1—Q9VNF6), and Habropoda laboriosa (HlMTA1—A0A0L7R1K5).
