New paper:
More than 2700 human 3′UTRs are highly conserved. These 3′UTRs are essential components in mRNA templates, as their deletion decreases protein activity without changing protein abundance. Highly conserved 3′UTRs help the folding of proteins with long IDRs.

mRNA 3′UTRs chaperone intrinsically disordered regions to control protein activity
More than 2,700 human mRNA 3′UTRs have hundreds of highly conserved (HC) nucleotides, but their biological roles are unclear. Here, we show that mRNAs with HC 3′UTRs mostly encode proteins with long intrinsically disordered regions (IDRs), including MYC, UTX, and JMJD3. These proteins are only fully active when translated from mRNA templates that include their 3′UTRs, raising the possibility of functional interactions between 3′UTRs and IDRs. Rather than affecting protein abundance or localization, we find that HC 3′UTRs control transcriptional or histone demethylase activity through co-translationally determined protein oligomerization states that are kinetically stable. 3′UTR-dependent changes in protein folding require mRNA-IDR interactions, suggesting that mRNAs act as IDR chaperones. These mRNAs are multivalent, a biophysical RNA feature that enables their translation in network-like condensates, which provide favorable folding environments for proteins with long IDRs. These data indicate that the coding sequence is insufficient for the biogenesis of biologically active conformations of IDR-containing proteins and that RNA can catalyze protein folding. ### Competing Interest Statement The authors have declared no competing interest.

I am thrilled to share the first manuscript from my group on identifying sequence and structural features promoting the condensation of RNAs that are organising highly interconnected RNA networks, thereby expanding our understanding of higher-order transcriptome assemblage.

Integrative profiling of condensation-prone RNAs during early development
Complex RNA–protein networks play a pivotal role in the formation of many types of biomolecular condensates. How intrinsic RNA features contribute to condensate formation however remains unclear. Here...
