Membrane mimetic systems in CryoEM: keeping membrane proteins in their native environment.

abstract：:The 5' m7GpppN cap plays an essential role in the life cycle of eukaryotic mRNA and is required for efficient pre-mRNA splicing, export, stability and translation. Nascent pre-mRNA is capped through a series of three enzymatic steps that result in a 5' N7-methyl guanosine linked by an inverted 5'-5' triphosphate bridg...
