Ultra-high-throughput analysis of functional biomolecules using in vitro selection and bioinformatics
2020
Kojima, Takaaki
Functional analysis of biomolecules, including nucleic acids and proteins, is important for understanding biological mechanisms in living cells such as gene expression and metabolism. To analyze diverse biomolecular functions, large-scale screening systems for biomolecules have been developed for various applications such as to improve enzyme activity and identify target binding molecules. One of these systems, the Bead Display system, utilizes emulsion technology and is a powerful tool for rapidly screening functional nucleic acids or proteins in vitro. Furthermore, an analytical pipeline that consists of genomic systematic evolution of ligands by exponential enrichment (gSELEX)-Seq, gene expression analysis, and bioinformatics was shown to be a robust platform for comprehensively identifying genes regulated by a transcription factor. This review provides an overview of the biomolecular screening methods developed to date.
