However, the mechanisms underlying CRC progression remain to be fully understood. In this work, a recently identified m6A-modified RNA reader protein Proline-rich Coiled-coil 2a (PRRC2A) is markedly upregulated in CRC, and intestinal epithelium-specific deletion of Prrc2a significantly suppressed tumor cell growth, stemness, and migratory capacity, while its overexpression promoted these behaviors. Through multiomics analysis, PRRC2A directly targeted CSNK1E (encoding CK1􀀂), maintaining its RNA stability in an m6A-dependent manner, and that elevated CK1􀀂 can concomitantly result in activation ofthe WNT and YAP signaling pathways. Interestingly, PRRC2A is directly regulated by the transcription factor ATF1 in its promoter. In summary, the work reveals a novel mechanism by which m6A reader PRRC2A promotes colorectal cancer progression via CK1􀀂 and aberrant upregulation ofWNT and YAP signaling. Therefore, PRRC2A and CK1􀀂 can be potential therapeutic targets for treating CRC.  \n1. Introduction  \nColorectal cancer (CRC) is a common digestive tract tumor with the third highest incidence rate and the second highest mortality rate among cancers, posing a serious threat to human life and health worldwide. [1,2] Understanding the mechanism underlying cancer progression is the foundation for the development of successful strategies for effective cancer prevention and management. N6-methyladenosine (m6A) modification is the most prevalent internal modification in eukaryotic mRNAs, and its dysregulation plays a critical role in promoting cancer progression. [3–5] m6A modifications of target RNAs need tobe recognized by m6A reader proteins to regulate RNA export, splicing, translation, and degradation. [3,6] Several m6A reader  \nX. Wu, Z.
