A polar ring endows improved specificity to an antibody fragment

Schaefer ZP, Bailey LJ, Kossiakoff AA

Protein Sci. 2016 07;25(7):1290-8

PMID: 27334407

Abstract

Engineering monovalent Fab fragments into bivalent formats like IgGs or F(ab’)2 can lead to aggregation presumably because of nonspecific off-target interactions that induce aggregation. In an effort to further understand the molecular determinants of nonspecific interactions for engineered antibodies and natively folded …

Conformational Chaperones for Structural Studies of Membrane Proteins Using Antibody Phage Display with Nanodiscs

Dominik PK, Borowska MT, Dalmas O, Kim SS, Perozo E, Keenan RJ, Kossiakoff AA

Structure 2016 Feb;24(2):300-9

PMID: 26749445

Abstract

A major challenge in membrane biophysics is to define the mechanistic linkages between a protein’s conformational transitions and its function. We describe a novel approach to stabilize transient functional states of membrane proteins in native-like …

Protein targeting. Structure of the Get3 targeting factor in complex with its membrane protein cargo

Mateja A, Paduch M, Chang HY, Szydlowska A, Kossiakoff AA, Hegde RS, Keenan RJ

Science 2015 Mar;347(6226):1152-5

PMID: 25745174

Abstract

Tail-anchored (TA) proteins are a physiologically important class of membrane proteins targeted to the endoplasmic reticulum by the conserved guided-entry of TA proteins (GET) pathway. During transit, their hydrophobic transmembrane domains (TMDs) are chaperoned by …

Nuclear pores. Architecture of the nuclear pore complex coat

Stuwe T, Correia AR, Lin DH, Paduch M, Lu VT, Kossiakoff AA, Hoelz A

Science 2015 Mar;347(6226):1148-52

PMID: 25745173

Abstract

The nuclear pore complex (NPC) constitutes the sole gateway for bidirectional nucleocytoplasmic transport. Despite half a century of structural characterization, the architecture of the NPC remains unknown. Here we present the crystal structure of a …

Engineering synthetic antibody binders for allosteric inhibition of prolactin receptor signaling

Rizk SS, Kouadio JL, Szymborska A, Duguid EM, Mukherjee S, Zheng J, Clevenger CV, Kossiakoff AA

Cell Commun. Signal 2015 Jan;13:1

PMID: 25589173

Abstract

BACKGROUND: Many receptors function by binding to multiple ligands, each eliciting a distinct biological output. The extracellular domain of the human prolactin receptor (hPRL-R) uses an identical epitope to bind to …
