Genes affected

EIF4A1 (HGNC:3282): (eukaryotic translation initiation factor 4A1) Enables double-stranded RNA binding activity. Predicted to be involved in cytoplasmic translational initiation. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

EIF4A1 links:

SENP3-EIF4A1 (HGNC:49182): (SENP3-EIF4A1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring SUMO1/sentrin/SMT3 specific peptidase 3 (SENP3) and eukaryotic translation initiation factor 4A1 (EIF4A1) genes on chromosome 17. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Mar 2011]
