CD209 or CLEC4L (C-type lectin domain family 4 member L) is a single-pass type II transmembrane protein and a member of the C-type lectin superfamily.  It is also referred to as DC-SIGN (Dendritic cell-specific ICAM-3-grabbing non-integrin 1). CLEC4L is expressed on the surface of dendritic cells and macrophages. CLEC4L is involved in the innate immune system and recognizes numerous evolutionarily divergent pathogens ranging from parasites to viruses with a large impact on public health. CLEC4L is organized into three distinct domains: an N-terminal transmembrane domain, a tandem-repeat neck domain and C-type lectin carbohydrate recognition domain. The extracellular region consisting of the C-type lectin and neck domains has a dual function as a pathogen recognition receptor and a cell adhesion receptor by binding carbohydrate ligands on the surface of microbes and endogenous cells. The neck region is important for homo-oligomerization which allows the receptor to bind multivalent ligands with high avidity. Variations in the number of 23 amino acid repeats in the neck domain of CLEC4L are rare but have a significant impact on ligand binding ability. This gene is closely related in terms of both sequence and function to a neighboring gene often referred to as L-SIGN. DC-SIGN and L-SIGN differ in their ligand-binding properties and distribution

Product Details

 

Gene Symbol: CLEC4L; CD209; CDSIGN; DC-SIGN; DC-SIGN1

 

NCBI Gene ID: 30835

 

Uniprot Entry: O9NNX6

 

Construct Details: Full length human CD209 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 1215 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
