additional information | the upstream WHEP pair of EPRS directs high-affinity binding to GAIT element-bearing mRNAs, while the overlapping, downstream pair binds NSAP1, which inhibits mRNA binding. Interaction of EPRS with ribosomal protein L13a and GAPDH induces a conformational witch that rescues mRNA binding and restores translational control, interaction analysis, overview | Homo sapiens | ? | - |
