Genes affected

EIF4E2 (HGNC:3293): (eukaryotic translation initiation factor 4E family member 2) Enables ubiquitin protein ligase binding activity. Involved in positive regulation of miRNA mediated inhibition of translation. Acts upstream of or within negative regulation of translation. Located in P-body. Part of mRNA cap binding activity complex. [provided by Alliance of Genome Resources, Apr 2022]
