Mannose-Binding Lectin Deficiency Is Associated with Myocardial Infarction: The HUNT2 Study in Norway

PLoS ONE, 2012
Objectives Mannose-binding lectin (MBL) and ficolins activate the complement cascade, which is involved in atherogenesis. Based on a pilot study, we hypothesized that functional polymorphisms in the MBL gene (MBL2) leading to dysfunctional protein are ...

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Burkholderia cenocepacia BC2L-C is a super lectin with dual specificity and proinflammatory activity.

PLoS Pathogens, 2011
Lectins and adhesins are involved in bacterial adhesion to host tissues and mucus during early steps of infection. We report the characterization of BC2L-C, a soluble lectin from the opportunistic pathogen Burkholderia cenocepacia, which has two distinct

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

The FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

Role of the Mannose‐Binding Lectin in Innate Immunity [PDF]

The Journal of Infectious Diseases, 2003
The ability to recognize infectious agents from self is intrinsic to innate immunity. One basic tenet of innate immunity is the evolution of classes of molecules that are termed "pattern-recognition" receptors and molecules. Many pattern-recognition molecules conspire together to protect the host in the first minutes and hours after exposure to an ...

Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes

The FEBS Journal, EarlyView.
C‐type lectins (CTLs) are involved in the detection of viral/microbial carbohydrates. We studied a family of soluble CTLs in the mosquito Aedes aegypti, which acts as a vector for viruses like dengue and Zika. Using crystallography, biophysics, and structure prediction approaches, we found that these proteins consistently pair together in the same ...

Computational insights into the circular permutation roles on ConA binding and structural stability

Current Research in Structural Biology
The mechanisms behind Concanavalin A (ConA) circular permutation have been under investigation since 1985. Although a vast amount of information is available about this lectin and its applications, the exact purpose of its processing remains unclear.

Mannose binding lectin: a biomarker of systemic lupus erythematosus disease activity

Arthritis Research & Therapy, 2012
IntroductionA role for mannose binding lectin (MBL) in autoimmune diseases has been demonstrated earlier and elevated level of MBL has been shown in systemic lupus erythematosus (SLE) patients.

A Novel Diagnostic Approach for Hepatocellular Carcinoma Using Glycosylated Ferritin

Hepatology Research, EarlyView.
The percentage of glycosylated ferritin relative to total ferritin (%GF) is a novel biomarker for hepatocellular carcinoma (HCC), showing diagnostic performance comparable to that of AFP and DCP. We developed the GFAD index by integrating age, sex, %GF, AFP, and DCP, achieving improved diagnostic accuracy with high sensitivity and specificity. ABSTRACT

High mannose-binding antiviral lectin PFL from Pseudomonas fluorescens Pf0-1 promotes cell death of gastric cancer cell MKN28 via interaction with α2-integrin.

PLoS ONE, 2012
Novel anti-HIV lectin family which shows a strict binding specificity for high mannose glycans has been found in lower organisms. The bacterial orthologue has been identified in the genome of Pseudomonas fluorescens Pf0-1 and the gene coding a putative ...
