Research Ins]i[ghts: Nanion’s Transporter Webinar Series 2021

Join us over the course of a year as we dive into a series of 5 sessions (a collective total of 10 scientific presentations/talks; representing academia & industry alike) scheduled across 2021. Whether you join us from an academic or industry setting, we invite you to join us a cross the course of the year to dive deep into all things transporters. Our aim is to provide a unique platform for researchers globally to share their work and engage in meaningful active discussions. All talks will be live and accessible on-demand upon completion of the scheduled event.


06.05.2021 - Secondary transport inhibition and regulation by SSM-electrophysiology

Session Abstract: 

Secondary active transporters utilize existing concentration gradients in cells for the uphill transport of molecules. As the coupled substrates are typically ions, mostly sodium or protons, many of these transporters are electrogenic. Their characteristics can be investigated using electrophysiological techniques like SSM-based electrophysiology. In the second session of the Transporter Webinar Series we meet Christine Ziegler and Camilo Perez, who share their stories about using this technology to investigate inhibition and regulation of secondary active transporters.

Speakers: 

Title: From K+ coupling to K+ regulation in secondary osmolyte transporters

Professor Dr. Christine Ziegler
(University of Regensburg, Faculty of Biology and Pre-Clinics, Institute of Biophysics and physical Biochemistry, Structural Biology-Biophysics II)

Abstract: 

Title: Selection of transporter-targeted inhibitory nanobodies by SSM-based electrophysiology 

Professor Dr. Camilo Perez
(University of Basel, Biozentrum, Center for Molecular Life Sciences)

Abstract: 

Single domain antibodies (nanobodies) have been extensively used in machanistic and structural studies of protein and pose an enormous potential as tools for developing clinical therapies, many of which depend on inhibition of membrane proteins such as transporters.

However, most of the methods used to determine inhibition of transport activity are difficult to perform in high-throughput routines and depend on labeled substrates availability. This complicates the screening of large nanobody libraries. Solid-supported membrane (SSM) electrophysiology to select inhibitory and non-inhibitory nanobodies targeting an electrogenic secondary transporter and to calculate nanobodies inhibitory constants. This technique may be especially useful for selecting inhibitory nanobodies targeting transporters for which labeled substrates are not available.
