The N-terminal region of photocleavable peptides that bind HLA-DR1 determines the kinetics of fragment release. [PDF]

open access: yesPLoS ONE, 2018
Major Histocompatibility Complex class II (MHC-II) molecules bind peptides and present them to receptors on CD4+ T cells as part of the immune system's surveillance of pathogens and malignancy.

From Synthetic Fragments of Endogenous Three-Finger Proteins to Potential Drugs

open access: yesFrontiers in Pharmacology, 2019
The proteins of the Ly6 family have a three-finger folding as snake venom α-neurotoxins, targeting nicotinic acetylcholine receptors (nAChRs), and some of them, like mammalian secreted Ly6/uPAR protein (SLURP1) and membrane-attached Ly-6/neurotoxin ...

Active Transport of Peptides Across the Intact Human Tympanic Membrane. [PDF]

open access: yes, 2018
We previously identified peptides that are actively transported across the intact tympanic membrane (TM) of rats with infected middle ears. To assess the possibility that this transport would also occur across the human TM, we first developed and ...

Functionally important segments in proteins dissected using Gene Ontology and geometric clustering of peptide fragments [PDF]

open access: yes, 2008
We have developed a geometric clustering algorithm using backbone \varphi,\psi angles to group conformationally similar peptide fragments of any length.

Fibrillisation of hydrophobically modified amyloid peptide fragments in an organic solvent [PDF]

open access: yes, 2007
The self-assembly of a hydrophobically modified fragment of the amyloid beta(A beta) peptide has been studied in methanol. The peptide FFKLVFF is based on A beta(16-20) extended at the N terminus by two phenylalanine residues.

The Synthetic Antimicrobial Peptide 19-2.5 Interacts with Heparanase and Heparan Sulfate in Murine and Human Sepsis.

open access: yesPLoS ONE, 2015
Heparanase is an endo-β-glucuronidase that cleaves heparan sulfate side chains from their proteoglycans. Thereby, heparanase liberates highly potent circulating heparan sulfate-fragments (HS-fragments) and triggers the fatal and excessive inflammatory ...

Peptide‐Guided Assembly of Repeat Protein Fragments [PDF]

open access: yesAngewandte Chemie International Edition, 2018
AbstractHerein, we present the peptide‐guided assembly of complementary fragments of designed armadillo repeat proteins (dArmRPs) to create proteins that bind peptides not only with high affinity but also with good selectivity. We recently demonstrated that complementary N‐ and C‐terminal fragments of dArmRPs form high‐affinity complexes that resemble ...

A Novel Urinary Proteomics Classifier for Non-Invasive Evaluation of Interstitial Fibrosis and Tubular Atrophy in Chronic Kidney Disease

open access: yesProteomes, 2021
Non-invasive urinary peptide biomarkers are able to detect and predict chronic kidney disease (CKD). Moreover, specific urinary peptides enable discrimination of different CKD etiologies and offer an interesting alternative to invasive kidney biopsy ...

Comparative Analysis of the Major Polypeptides from Liver Gap Junctions and Lens Fiber Junctions [PDF]

open access: yes, 1982
Gap junctions from rat liver and fiber junctions from bovine lens have similar septilaminar profiles when examined by thin-section electron microscopy and differ only slightly with respect to the packing of intramembrane particles in freeze-fracture ...
