DC-SIGN1A (CD209)

Expression-ready ORF Clones

Alias : DCSIGN1, CD209, CD209A, CDSIGN, CLEC4L

Dendritic cell-specific ICAM-3 grabbing nonintegrin.
CD209 molecule.

DC-specific intercellular adhesion molecule-grabbing nonintegrin (DC-SIGN) is a C-type lectin involved in the capture of different pathogens. DC-SIGN recognizes distinct carbohydrate structures such as the viral envelope glycoproteins expressed by the HIV1 [1], hepatitis C virus, and Ebola virus. Non-viral pathogens can also interact with DC-SIGN including yeast, parasites and bacteria, such as Mycobacteria tuberculosis [2]. Following recognition, DC-SIGN internalizes the pathogens for processing and antigen presentation. The central feature of the pathogens recognized by DC-SIGN is that they misuse DC-SIGN by distinct mechanisms that either circumvent antigen processing or alter TLR-mediated signaling, skewing T-cell responses [3].
