What's a GeneRIF?

Data show that mutations of eIF3 subunits, g/Tif35 and i/Tif34 diminish induction of GCN4 expression.
Title: The RNA recognition motif of eukaryotic translation initiation factor 3g (eIF3g) is required for resumption of scanning of posttermination ribosomes for reinitiation on GCN4 and together with eIF3i stimulates linear scanning.
