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 ...

Algorithms for the analysis of MALDI peptide mass fingerprint spectra for proteomics [PDF]

open access: yes, 2005
In this study we present a simple algorithm which allows accurate estimates of the similarity between peptide fingerprint mass spectra from matrix assisted laser desorption/ionization (MALDI) spectrometers.

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 ...

Protein GB1 folding and assembly from structural elements. [PDF]

open access: yes, 2009
Folding of the Protein G B1 domain (PGB1) shifts with increasing salt concentration from a cooperative assembly of inherently unstructured subdomains to an assembly of partly pre-folded structures.

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 ...

A Formylglycine-Peptide for the Site-Directed Identification of Phosphotyrosine-Mimetic Fragments

open access: yes, 2022
Discovery of protein-binding fragments for precisely defined binding sites is an unmet challenge so far. Here, we investigate formylglycine as a molecular probe for the sensitive detection of fragments binding to a spatially defined protein site ...
