Experiments in micro-patterned model membranes support the narrow escape theory

Autor: Elisabeth Meiser, Reza Mohammadi, Nicolas Vogel, David Holcman, Susanne F. Fenz

Publikováno v: Communications Physics, Vol 6, Iss 1, Pp 1-10 (2023)

Abstract The narrow escape theory (NET) predicts the escape time distribution of Brownian particles confined to a domain with reflecting borders except for one small window. Applications include molecular activation events in cell biology and biophys

N-glycosylation enables high lateral mobility of GPI-anchored proteins at a molecular crowding threshold

Autor: Andreas J. W. Hartel, Marius Glogger, Nicola G. Jones, Wasim Abuillan, Christopher Batram, Anne Hermann, Susanne F. Fenz, Motomu Tanaka, Markus Engstler

How molecular crowding affects membrane protein diffusion and function is not known. Here the authors measure diffusion of variant surface glycoprotein on trypanosomes and discover a molecular crowding threshold that limits diffusion, and find that N

Association Rates of Membrane-Coupled Cell Adhesion Molecules

Autor: Ana-Sunčana Smith, Kheya Sengupta, Udo Seifert, Timo Bihr, Susanne F. Fenz, Rudolf Merkel, Erich Sackmann

Publikováno v: Biophysical Journal. 107(11):L33-L36

Thus far, understanding how the confined cellular environment affects the lifetime of bonds, as well as the extraction of complexation rates, has been a major challenge in studies of cell adhesion. Based on a theoretical description of the growth cur

Measuring the Invisible: Determining the Size of Growing Nanodomains Using the 'Inverse FCS'

Autor: Cornelia Monzel, Ana-Sunčana Smith, Susanne F. Fenz

Publikováno v: Biophysical journal. 112(11)

Molecular recruitment into functional domains in the cell plasma membrane is an important prerequisite for many cellular processes, such as cell signaling, cell-matrix adhesion, or the formation of synapses. High precision measurements of the origin

The integrity of living tissues is maintained by adhesion domains of trans-bonds formed between cadherin proteins residing on opposing membranes of neighbouring cells. These domains are stabilized by lateral cis-interactions between the cadherins on

Structural basis for the shielding function of the dynamic trypanosome variant surface glycoprotein coat

The most prominent defence of the unicellular parasite Trypanosoma brucei against the host immune system is a dense coat that comprises a variant surface glycoprotein (VSG). Despite the importance of the VSG family, no complete structure of a VSG has

The protein density in biological membranes can be extraordinarily high, but the impact of molecular crowding on the diffusion of membrane proteins has not been studied systematically in a natural system. The diversity of the membrane proteome of mos

Cadherins are major cell-cell adhesion molecules in vertebrate tissue. They play a vital role in the development and maintenance of multicellular organisms. Cadherins show homophilic as well as heterophilic binding to members of their subfamily with
