Integrated mimicry of B cell antibody mutagenesis using yeast homologous recombination.

Abstract excerpt

Antibody affinity maturation proceeds in vivo via a combination of point mutations, insertions, deletions, and combinatorial shuffling of light chains or portions of the heavy chain, thereby reducing the probability of trapping in local affinity optima in sequence space. In vivo homologous recombination in yeast can be exploited to mimic the broad spectrum of mutational types deployed by B cells, incorporating...
