CLEC2, also termed CLEC-1B, is a C-type lectin-like receptor. CLEC2 is highly expressed on resting platelets and megakaryocytes, and expressed at lower levels on several hematopoietic cells including monocytes, macrophages, dendritic cells, and granulocytes. The first ligand identified for CLEC2 was rhodocytin, snake venom toxin. Rhodocytin is a strong platelet activator, and this effect is mediated by CLEC2, which has a single cytoplasmic YXXL sequence known as a hem-immunoreceptor tyrosine-based activation motif (ITAM). Exposure of platelets to rhodocytin leads to tyrosine phosphorylation of the ITAM-like motif and Syk-dependent platelet activation. Podoplanin, also termed GP38 is an endogenous ligand of CLEC2. This molecule was found to be expressed on the surface of tumor cells and facilitates tumor metastasis by inducing platelet aggregation. Podoplanin is also expressed on endothelial cells, and mice deficient in this protein show abnormal patterns of lymphatic vessel formation. In addition, CLEC2 functions as an activating receptor on monoyctes and neutrophils to induce phagocytosis and proinflammatory cytokine production. CLEC2 enhances the expansion of TCR-stimulated T cells by increasing their survival through enhanced expression of anti-apoptotic proteins. Also, CLEC2 modulates the capacity of T cells to home to lymph nodes and stimulates natural killer cell mediated cytotoxicity.
Product Details
- Source
- Mouse CLEC2, amino acids (Gln57-Leu229) (Accession# NP_064369.1), was expressed in CHO cells with a C-terminal human IgG1 Fc tag.
- Molecular Mass
- The 409 amino acid recombinant protein has a predicted molecular mass of approximately 46.7 kD. The protein migrates at about 60 kD by SDS-PAGE in DTT-reducing conditions and about 120 kD in non-reducing conditions. The predicted N-terminal amino acid is Gln.
- Purity
- >95%, as determined by Coomassie stained SDS-PAGE.
- Formulation
- 0.22 µm filtered protein solution is in PBS.
- Endotoxin Level
- Less than 1.0 EU per µg of protein as determine by the LAL method.
- Concentration
- 25 µg size is bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
- Activity
- Recombinant mouse CLEC2, when coated on a plate (2 µg/ml, 100 µl/well) is able to bind biotinylated mouse GP38 in a dose dependent manner with an apparent Kd <5.0 nM.
