Laminin-α4 and Integrin-Linked Kinase Mutations Cause Human Cardiomyopathy Via Simultaneous Defects in Cardiomyocytes and Endothelial Cells
Ralph Knöll,Ruben Postel,Jianming Wang,Ralph Krätzner,Gerrit Hennecke,Andrei M. Vacaru,Padmanabhan Vakeel,Cornelia Schubert,Kenton K. Murthy,Brinda K. Rana,Dieter Kube,Gudrun Knöll,Katrin Schäfer,Takeharu Hayashi,Torbjorn Holm,Akinori Kimura,Nicholas J. Schork,Mohammad R.

Chien,Jeroen Bakkers +28 more
TL;DR: This is the first report on mutations in the laminin, integrin, and ILK system in humanCardiomyopathy, which has consequences for endothelial cells as well as for cardiomyocytes, thus providing a new genetic basis for dilated carduomyopathy in humans.
Journal ArticleDOI
The cystine knot of a squash-type protease inhibitor as a structural scaffold for Escherichia coli cell surface display of conformationally constrained peptides.
TL;DR: These results demonstrate that E.coli cell surface display of conformationally constrained peptides tethered to the EETI-II cystine knot scaffold has the potential to become an effective technique for the rapid isolation of small peptide molecules from combinatorial libraries that bind with high affinity to acceptor molecules.
Journal ArticleDOI
RNASET2-deficient cystic leukoencephalopathy resembles congenital cytomegalovirus brain infection
Marco Henneke,Simone Diekmann,Andreas Ohlenbusch,Jens Kaiser,Volkher Engelbrecht,Alfried Kohlschütter,Ralph Krätzner,Marcos Madruga-Garrido,M. Mayer,Lennart Opitz,Diana Rodriguez,Diana Rodriguez,Franz Rüschendorf,Johannes Schumacher,Johannes Schumacher,Holger Thiele,Sven Thoms,Robert Steinfeld,Peter Nürnberg,Jutta Gärtner +19 more
TL;DR: It is shown that loss-of-function mutations in the gene encoding the RNASET2 glycoprotein lead to cystic leukoencephalopathy, an autosomal recessive disorder with an indistinguishable clinical and neuroradiological phenotype.
Journal ArticleDOI
Sequence Requirements of the GPNG β-Turn of the Ecballium elaterium Trypsin Inhibitor II Explored by Combinatorial Library Screening
TL;DR: Substantial amounts of misfolded byproducts were obtained upon refolding of these variants corroborating the importance of the wild type EETI-II GPNG sequence to direct quantitative formation of the cystine knot architecture.
Journal ArticleDOI
Global genetic analyses reveal strong inter-ethnic variability in the loss of activity of the organic cation transporter OCT1
Tina Seitz,Robert Stalmann,Nawar Dalila,Jiayin Chen,Sherin Pojar,Joao N. Dos Santos Pereira,Ralph Krätzner,Jürgen Brockmöller,Mladen V. Tzvetkov +8 more
TL;DR: Comprehensive genetic analyses showed strong global variations in the frequency of loss of OCT1 activity with selection pressure for maintainingoct1 activity in East Asia and Oceania.
