| Short Description: |
Recombinant-Human LAG3/CD223-C-His-Avi protein was developed from hek293 and has a target region of C-His-Avi. For use in research applications. |
| Conjugation: |
Biotin |
| Formulation: |
Lyophilised from 0.2 µm filtered PBS solution pH7.4. |
| Dilution Range: |
Upon receipt centrifuge vial to ensure maximal product extraction, recommended: 20sec, 5K RPM |
| Storage Instruction: |
The lyophilized protein is stable for at least 1 year from date of receipt at-20°C. |
| Endotoxin: |
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). |
| Gene Symbol: |
LAG3 |
| Gene ID: |
3902 |
| Uniprot ID: |
LAG3_HUMAN |
| Immunogen Region: |
Leu23-Gly434 |
| Immunogen: |
DNA sequence encoding Human LAG3/CD223 including a C-His-Avi tag was expressed in HEK293 Cells. The recombinant protein was then biotinylated site specific using the AVItag biotinylation technology. |
| Post Translational Modifications | Lymphocyte activation gene 3 protein: Proteolytically cleaved by ADAM10 and ADAM17 within the connecting peptide region, leading to release of Secreted lymphocyte activation gene 3 protein (sLAG-3). ADAM10 mediates constitutive cleavage, but cleavage increases following T-cell activation, whereas shedding by ADAM17 is induced by TCR signaling in a PRKCQ-dependent manner. |
| Function | Lymphocyte activation gene 3 protein: Inhibitory receptor on antigen activated T-cells. Delivers inhibitory signals upon binding to ligands, such as FGL1. FGL1 constitutes a major ligand of LAG3 and is responsible for LAG3 T-cell inhibitory function. Following TCR engagement, LAG3 associates with CD3-TCR in the immunological synapse and directly inhibits T-cell activation. May inhibit antigen-specific T-cell activation in synergy with PDCD1/PD-1, possibly by acting as a coreceptor for PDCD1/PD-1. Negatively regulates the proliferation, activation, effector function and homeostasis of both CD8(+) and CD4(+) T-cells. Also mediates immune tolerance: constitutively expressed on a subset of regulatory T-cells (Tregs) and contributes to their suppressive function. Also acts as a negative regulator of plasmacytoid dendritic cell (pDCs) activation. Binds MHC class II (MHC-II).the precise role of MHC-II-binding is however unclear. Secreted lymphocyte activation gene 3 protein: May function as a ligand for MHC class II (MHC-II) on antigen-presenting cells (APC), promoting APC activation/maturation and driving Th1 immune response. |
