Chakraborty K, Chatila M, Sinha J, Shi Q, Poschner B, Sikor M, et al.
Cell
. 2010 Jul;
142(1):112-22.
PMID: 20603018
GroEL and GroES form a chaperonin nano-cage for single protein molecules to fold in isolation. The folding properties that render a protein chaperonin dependent are not yet understood. Here, we...

Poschner B, Fischer K, Herrmann J, Hofmann M, Langosch D
Mol Membr Biol
. 2009 Nov;
27(1):1-10.
PMID: 19939203
The transmembrane domains of fusion proteins are known to be important for their fusogenic activity. In an effort to systematically investigate the structure/function relationships of transmembrane domains we had previously...

Poschner B, Langosch D
Protein Sci
. 2009 Jul;
18(8):1801-5.
PMID: 19569191
Acylation of proteins is known to mediate membrane attachment and to influence subcellular sorting. Here, we report that acylation can stabilize secondary structure. Circular dichroism spectroscopy showed that N-terminal attachment...

Poschner B, Quint S, Hofmann M, Langosch D
J Mol Biol
. 2009 Jan;
386(3):733-41.
PMID: 19154744
The transmembrane domains of fusion proteins are known to be functionally important and display an overabundance of helix-destabilizing Ile and Val residues. In an effort to systematically study the relationship...

Stelzer W, Poschner B, Stalz H, Heck A, Langosch D
Biophys J
. 2008 May;
95(3):1326-35.
PMID: 18456822
SNARE proteins mediate fusion of intracellular eukaryotic membranes and their alpha-helical transmembrane domains are known to contribute to lipid bilayer mixing. Synthetic transmembrane domain peptides were previously shown to mimic...

Hofmann M, Poschner B, Hauser S, Langosch D
Biochemistry
. 2007 Mar;
46(13):4204-9.
PMID: 17346063
LV-peptides mimic the in vitro fusogenicity of synthetic fusion protein transmembrane domains. The original versions of these peptides consist of a variable hydrophobic core (containing leucine and/or valine residues (LV))...

J Mol Biol
. 2006 Oct;
364(5):1048-60.
PMID: 17054985
SNARE proteins mediate intracellular fusion of eukaryotic membranes. Some SNAREs have previously been shown to dimerise via interaction of their transmembrane domains. However, the functional significance of these interactions had...
