Definition

The mRNA display method is an in vitro selection technique that allows the isolation of functional proteins from large combinatorial libraries of polypeptide variants (Roberts and Szostak 1997; Nemoto et al. 1997). This technology has been used to determine the probability of occurrence of proteins with a specific function in the vast sequence space of all possible polypeptides.

Overview

Functional proteins might have originated from early peptides that initially were synthesized as random amino acid polymers. In order to test the likelihood of such random mixtures containing functional polypeptides, a large number of polypeptides need to be tested as this likelihood might be low. While there are numerous methods to sample mixtures of proteins, the approach that can search the largest number of mutants is most suited to address this question. mRNA display is a technique that can sample libraries of up to 10 13randomized protein variants. In mRNA display, the messenger RNA...
