Protein Chimerization: A New Frontier for Engineering Protein Therapeutics with Improved Pharmacokinetics

DARPins: a new generation of protein therapeutics.

DARPins (designed ankyrin repeat proteins) are a novel class of binding molecules with the potential to overcome limitations of monoclonal antibodies, hence allowing novel therapeutic approaches. DARPins are small, single domain proteins (14 kDa) which can be selected to bind any given target protein with high affinity and specificity. These characteristics make them ideal agonistic, antagonist...

Protein engineering for improved pharmacologic characteristics of established monoclonal antibody-based therapeutics.

Sortase-mediated protein ligation: a new method for protein engineering.

Sortase (SrtA), a transpeptidase from Staphylococcus aureus, catalyzes a cell-wall sorting reaction at an LPXTG motif by cleaving between threonine and glycine and subsequently joining the carboxyl group of threonine to an amino group of pentaglycine on the cell wall peptidoglycan. We have applied this transpeptidyl activity of sortase to in vitro protein ligation. We found that in the presence...

Introduction to current and future protein therapeutics: a protein engineering perspective.

Protein therapeutics and its enabling sister discipline, protein engineering, have emerged since the early 1980s. The first protein therapeutics were recombinant versions of natural proteins. Proteins purposefully modified to increase their clinical potential soon followed with enhancements derived from protein or glycoengineering, Fc fusion or conjugation to polyethylene glycol. Antibody-based...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
