Genetically Encodable Bacterial Flavin Transferase for Fluorogenic Protein Modification in Mammalian Cells.

abstract：:Secondary structure formation of mRNA, caused by desynchronization of transcription and translation, is known to impact gene expression in vivo. Yet, inactivation of mRNA by secondary structures in cell-free protein expression is frequently overlooked. Transcription and translation rates are often not highly synchroni...
