Abstract
<p class="first" id="P2">Protein engineering is an emerging discipline that dovetails
modern molecular biology
techniques with high-throughput screening, laboratory evolution technologies, and
computational approaches to modify sequence, structure, and in some cases, function
and properties of proteins. The ultimate goal is to develop new proteins with improved
or designer functions for use in biotechnology, medicine and basic research. One way
to engineer proteins is to change their solvent exposed regions through focused or
random ‘protein resurfacing’. In this review we explain what protein resurfacing is,
and discuss recent examples of how this strategy is used to generate proteins with
altered or broadened recognition profiles, improved stability, solubility, expression,
cell penetrating ability, and reduced immunogenicity. Additionally, we comment on
how these properties can be further improved using chemical resurfacing approaches.
Protein resurfacing will likely play an increasingly important role as more biologics
enter clinical use, and we present some arguments to support this view.
