Membraneless OT organelles enable mRNA-specific GCE in eukaryotes.

Membraneless OT organelles enable mRNA-specific GCE in eukaryotes.

OT organelles are designed organelles enriched in a suppressor tRNA/tRNA synthetase pair and a specific mRNA binding domain (MCP) by means of using an assembler protein (such as FUS and/or KIFs). A spatially distinct set of ribosomes associated with the OT organelle preferentially translates recruited mRNAs tagged with ms2 loops to yield the selected protein with the targeted site-specific noncanonical functionality.
