RRM1 and cancer: In the RNA pull‐down and mass spectrometry analysis, IGF2BP2 was identified, which binds RNA through its six characteristic RNA‐binding domains, including two RNA Recognition Motifs (RRM1 and RRM2) and four KH domains (KH1‐KH4).[38] IGF2BP2, a member of the m6A methylation reader protein family IGF2BPs, plays a crucial role in the development of cancer.
