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. Here, PRRC2A is linked to colorectal carcinoma.
