AIDS patients have increased surfactant protein D but normal mannose binding lectin levels in lung fluid. [PDF]

open access: yes, 2007
BACKGROUND: Surfactant protein D (SP-D) and Mannose Binding Lectin (MBL) are collectins that have opsonic and immunoregulatory functions, are found in lung fluid and interact with the human immunodeficiency virus (HIV).

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

open access: yesThe FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor‐like lectin

open access: yesThe FEBS Journal, EarlyView.
We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

Bacterial surface display of human lectins in Escherichia coli

open access: yesMicrobial Biotechnology
Lectin‐glycan interactions sustain fundamental biological processes involved in development and disease. Owing to their unique sugar‐binding properties, lectins have great potential in glycobiology and biomedicine.

Carbohydrate specificity of sea urchin sperm bindin: a cell surface lectin mediating sperm-egg adhesion. [PDF]

open access: yes, 1982
We have examined the carbohydrate specificity of bindin, a sperm protein responsible for the adhesion of sea urchin sperm to eggs, by investigating the interaction of a number of polysaccharides and glycoconjugates with isolated bindin.

Protein-carbohydrate interactions during fertilization [PDF]

open access: yes, 1998
Interaction between gametes during fertilization is at least in part regulated by carbohydrate moieties of the zona pellucida (ZP) and carbohydrate binding proteins of the sperm surface. This review focuses on the protein-carbohydrate interactions during

Recombinant Mannose-binding Lectin Protein and Anti-Mannose-binding Lectin Polyclonal Antibody Production

open access: yesJournal of Life Science, 2009
The innate immune system is important for the first line of host defence against infectious agents, which have penetrated the mechanical barriers. Mannose-binding lectin (MBL or mannan-binding protein, MBP) is a serum protein that is synthesized in the liver as a part of the acute phase response. MBL binds to carbohydrate structures presented by a wide

The fc fragment of IgMs binds C1q to activate the first step of the classical complement pathway, while inhibiting complement‐dependent cytotoxicity

open access: yesThe FEBS Journal, EarlyView.
Multimeric IgM‐fragment crystallizable region (Fc) fragments retain the ability to bind C1q and initiate the classical complement pathway, leading to C4 activation and deposition in vitro. However, the Fc cores can also inhibit complement‐dependent cytotoxicity by competing with surface‐bound antibodies for C1q engagement.

Jasmonate Modulates Strawberry Susceptibility to Anthracnose by Activating SnRK2.1 to Regulate the WRKY50‐JAZ5 Module

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Colletotrichum spp., hemibiotrophic fungal pathogens, threaten global strawberry production. Jasmonate (JA) regulates plant‐Colletotrichum interactions, but its mechanisms remain unclear. Here we demonstrate that both exogenous methyl jasmonate (MeJA) treatment and elevated endogenous MeJA levels increase strawberry susceptibility to ...
