Figure 3Analysis of the abundance distribution for (A) cytoplasmic, (B) mitochondrial, and (C) extracellular proteins across 5 age groups in C.elegans (Walther et al, 2015). Each age group was compared against a pool reference sample using SILAC (Ong et al, 2002). Distribution of protein fold changes for the different time points are shown as density plots and as as boxplots (inset); below the boxplots, asterisks mark the time points that show significantly different distribution of fold changes compared to the first time point (Mann-Whitney test p<0.01) Abundance variation of complex members for (D) three mitochondrial complexes (respiratory complex I, mitochondrial ribosome and mitochondrial import/export proteins). For each complex, the abundance variation of each member (colored in grey) over the 5 age groups is reported with the Δ SILAC ratio (difference between the experimental SILAC ratio of a time point and the SILAC ratio at day 1, left) and the CNV value (right). For each age group, the box plot (colored as the corresponding time-point in the panels A-B-C) represents the variance between the abundances of the complex members. Significant changes (Mann-Whitney test p<0.05) are marked with a red star (E) Variation of the mitochondrial proteome over the lifespan of C.elegans (day 1 and day 22). Respiratory chain complex I and mitochondrial ribosomal proteins are highlighted in green and purple, respectively (selected proteins, with extreme CNV values, are indicated) (F) Variation of the extracellular proteome abundance over the lifespan of C.elegans (day 1 and day 22). Four proteins have been selected (highlighted with a colored circle: purple for NAS-34, green for Y45F10C.4, blue for Vitellogenin-1, black for Y45F10C.2) for their slower or accelerated increase of abundance compared to the rest of extracellular proteins.

Figure 7A. In UPF3 paralog-dependent NMD, prior to UPF1 activation, CASC3-EJC enhances the presence of UPF3B and UPF2 on exon-exon junctions. UPF3A can replace UPF3B when UPF3B levels are insufficient. Black arrow at the top indicates that such enhanced UPF3 paralog and UPF2 recruitment to mRNA via EJC can later facilitate their assembly with UPF1 to form the NMD complex. B. Within the UPF complex that senses aberrant translation termination and activates NMD, UPF3 paralogs perform a function that is independent of its EJC binding. Perhaps, such a function involves their interaction with eRF3 (indicated by a dotted yellow line; Neu-Yilik et al., 2017). While it is possible that the EJC still plays a more direct role during this NMD activation step (indicated by a red dotted line with a question mark), such a function likely occurs independently of EJC-UPF3A/3B interaction. These events culminate in NMD in UPF3A/3B-dependent manner, which occurs at a higher probability than in absence of UPF3 paralogs (signified by a higher weight arrow). C. NMD can occur in UPF3A/3B-independent manner. It remains possible that the EJC can still communicate with the premature termination complex in a UPF3A/3B-, and possibly UPF2-independent manner (indicated by a red dotted line with a question mark) to elicit NMD. mRNAs are targeted to NMD at a lower probability in the absence of UPF3 paralogs (signified by a lower weight arrow).
