Probing the functions of the paramyxovirus glycoproteins F and HN with a panel of synthetic antibodies
Welch BD, Paduch M, Leser GP, Bergman Z, Kors CA, Paterson RG, Jardetzky TS, Kossiakoff AA, Lamb RA
J. Virol. 2014 Oct;88(20):11713-25
PMID: 25122782
Abstract
Paramyxoviruses are enveloped negative-strand RNA viruses that are significant human and animal pathogens. Most paramyxoviruses infect host cells via the concerted action of a tetrameric attachment protein (variously called HN, …

New Tricks for an Old Dimer
Wells JA, Kossiakoff AA
Cell Biology, Volume 344, Issue 6185, pp. 703-704
Abstract
Much of multicellular biology depends on communication through extracellular signaling molecules that bind to membrane receptors and trigger intracellular signaling events and cell behaviors. One of the first paradigm systems for understanding how polypeptide hormones bind and activate their receptors was …

Generating conformation-specific synthetic antibodies to trap proteins in selected functional states
Paduch M, Koide A, Uysal S, Rizk SS, Koide S, Kossiakoff AA
Methods 2013 Mar;60(1):3-14
PMID: 23280336
Abstract
A set of phage display sorting strategies and validation methodologies are presented that are capable of producing high performance synthetic antibodies (sABs) with customized properties. Exquisite control of antigen and conditions during the phage display selection process …

Substance P derivatives as versatile tools for specific delivery of various types of biomolecular cargo
Rizk SS, Misiura A, Paduch M, Kossiakoff AA
Bioconjug. Chem. 2012 Jan;23(1):42-6
PMID: 22175275
Abstract
The use of proteins or nucleic acids as therapeutic agents has been severely hampered by their intrinsic inability to cross the cell membrane. Moreover, common techniques for driving the delivery of macromolecules lack the ability to distinguish between healthy and …

Mechanism of activation gating in the full-length KcsA K+ channel
Uysal S, Cuello LG, Cortes DM, Koide S, Kossiakoff AA, Perozo E
Proc. Natl. Acad. Sci. U.S.A. 2011 Jul;108(29):11896-9
PMID: 21730186
Abstract
Using a constitutively active channel mutant, we solved the structure of full-length KcsA in the open conformation at 3.9 Å. The structure reveals that the activation gate expands about 20 Å, exerting a strain on …

Allosteric control of ligand-binding affinity using engineered conformation-specific effector proteins
Rizk SS, Paduch M, Heithaus JH, Duguid EM, Sandstrom A, Kossiakoff AA
Nat. Struct. Mol. Biol. 2011 Apr;18(4):437-42
PMID: 21378967
Abstract
We describe a phage display methodology for engineering synthetic antigen binders (sABs) that recognize either the apo or the ligand-bound conformation of maltose-binding protein (MBP). sABs that preferentially recognize the maltose-bound form of MBP …
