The functions and structures of these proteins were further analyzed; among them, we found that ANXA2 contains RNA‐binding sites[25] and plays an important role in various cancers, including BC.[25, 26, 27, 28, 29, 30] To further validate the binding of mtiRL to ANXA2, RNA pull‐down and RNA IP assays coupled with m7G IP were performed. Here, ANXA2 is linked to breast cancer.
