EIF3H activates competence. 2 / 2

"In plants, eIF3 non core subunit h (eIF3h) greatly elevates the reinitiation competence of mRNAs coding for the Arabidopsis basic zipper transcription factors (bZIPs) and several ARFs; while the 60S ribosomal protein L24B (RPL24B), which is encoded by SHORT VALVE1, lifts translation of uORF containing mRNAs that encode ARF3 (ETTIN) and ARF5."

"It was proposed that, by analogy with the function of yeast eIF3a and Tif32 discussed above, eIF3h (specifically its N-terminal part) might support efficient REI by preserving the competence of a fraction of uORF translating ribosomes to resume traversing downstream."
