Rabbit anti-Human DC-SIGNR/CD299 Monoclonal Antibody

Uniprot Id

Q9H2X3

Target Species

Human

Target Name

CLEC4M

Target Full Name

C-type lectin domain family 4 member M

Target Function

Probable pathogen-recognition receptor involved in peripheral immune surveillance in liver. May mediate the endocytosis of pathogens which are subsequently degraded in lysosomal compartments. Is a receptor for ICAM3, probably by binding to mannose-like carbohydrates.; (Microbial infection) Acts as an attachment receptor for Ebolavirus.; (Microbial infection) Acts as an attachment receptor for Hepatitis C virus.; (Microbial infection) Acts as an attachment receptor for HIV-1.; (Microbial infection) Acts as an attachment receptor for Human coronavirus 229E.; (Microbial infection) Acts as an attachment receptor for Human cytomegalovirus/HHV-5.; (Microbial infection) Acts as an attachment receptor for Influenzavirus.; (Microbial infection) Acts as an attachment receptor for SARS-CoV.; (Microbial infection) Acts as an attachment receptor for West-nile virus.; (Microbial infection) Acts as an attachment receptor for Japanese encephalitis virus.; (Microbial infection) Acts as an attachment receptor for Marburg virus glycoprotein.; (Microbial infection) Recognition of M.bovis by dendritic cells may occur partially via this molecule.

Target Background

This gene encodes a C-type lectin that functions in cell adhesion and pathogen recognition. This receptor recognizes a wide range of evolutionarily divergent pathogens with a large impact on public health, including tuberculosis mycobacteria, and viruses including Ebola, hepatitis C, HIV-1, influenza A, West Nile virus and the SARS-CoV acute respiratory syndrome coronavirus. The protein is organized into four distinct domains: a C-terminal carbohydrate recognition domain, a flexible tandem-repeat neck domain of variable length, a transmembrane region and an N-terminal cytoplasmic domain involved in internalization. This gene is closely related in terms of both sequence and function to a neighboring gene, CD209 (Gene ID: 30835), also known as DC-SIGN. The two genes differ in viral recognition and expression patterns, with this gene showing high expression in endothelial cells of the liver, lymph node and placenta. Polymorphisms in the tandem repeat neck domain are associated with resistance to SARS infection.
