YBX3 and cancer: EIF2S3, a subunit of the eukaryotic initiation factor 2 (eIF2), is critical in eukaryotic translation initiation involved in the rate‐limiting step in protein synthesis and translation deregulation, which is known to be important in cancer.[38] Our Co‐IP assay confirmed the protein interaction between EIF2S3 and YTHDF2/YBX3 (Figure 6D; Figure S8L,M, Supporting Information).
