Altered langerin function in individuals with the linked AsnAsp and LysIle polymorphisms may affect susceptibility to infection by micro-organisms. It is a condition characterized by the absence of Birbeck granules in epidermal Langerhans cells. Views Article Discussion Edit this page History.
W Tan, S L. Structural analysis shows that enhanced binding to GlcNAc may result from Ile packing against the N-acetyl group. Langerin with Asp and Ile shows no binding to 6SO4-Gal-terminated glycans and increased binding to GlcNAc-terminated structures, but overall decreased binding to glycans.
Despite the lack of Birbeck granules Langerhans cells are present in normal numbers and have normal morphologic characteristics and antigen-presenting capacity. Binds to high-mannose structures present on the envelope glycoprotein which is followed by subsequent targeting of the virus to the Birbeck granules leading to its rapid degradation. Asymmetric Unit Biological Assembly.

Induces the formation of Birbeck granules BGs ; is a potent regulator of membrane superimposition and zippering. For a guided tour on the structure components use FirstGlance. Toolbox Upload file Special pages Printable version Permanent link. Retrieved from ” http: Langerin binds a diverse range of carbohydrates including high mannose structures, fucosylated blood group antigens and glycans with terminal 4n333 galactose.

National Library of Medicine. Full crystallographic information is available from OCA. A commonly occurring single nucleotide polymorphism SNP in human langerin results in change of one of these lysine residues, Lys, to isoleucine.
Langerin, a C-type lectin on Langerhans cells, mediates carbohydrate-dependent uptake of pathogens in the first step of antigen presentation to the adaptive immune system.
Common polymorphisms in human 4n333 change specificity for glycan ligands.
4n33 – Proteopedia, life in 3D
Major receptor on primary Langerhans cells for Candida species, Saccharomyces species, and Malassezia furfur. Protects against human immunodeficiency virus-1 HIV-1 infection. Structural highlights 4n33 is a 4 chain structure with 44n33 from Human.
Glycan array screening reveals that this amino acid change abolishes binding to oligosaccharides with terminal 6SO4-Gal and enhances binding to oligosaccharides with terminal GlcNAc residues. Binds to sulfated as well as mannosylated glycans, keratan sulfate KS and beta-glucans.
