Fig. 8. A model of uORF-mediated translational control of SAC51
expression via ACL5 function. SAC51 and sac51-d
transcripts are represented as horizontal lines, the fourth uORF as a dark
gray box, uORFs (except the fourth uORF) as light gray boxes, the main ORF as
a white box and SAC51 bHLH proteins as hatched circles. Small (40S) and large
(60S) ribosomal subunits are indicated by small and large black circles,
respectively.
