Proteins with long IDRs are prone to misfolding during protein synthesis.
This is prevented by mRNA 3′UTRs that act as mRNA-based IDR chaperones.

Highly conserved mRNA 3′ UTRs act as co-translational chaperones for intrinsically
disordered regions (IDRs), preventing inter-domain misfolding and enabling biogenesis
of fully active proteins.

A fungal long non-coding RNA from Magnaporthe oryzae translocates into rice cells to sequester a host microRNA that normally represses PKR1, a negative immunity regulator, thereby facilitating infection and revealing a widespread RNA-based pathogen–host interaction mechanism.
