关键词: 淋巴细胞活化基因3, Lymphocyte activation gene 3 protein, LAG3, LAG-3, Protein FDC, CD223, Human CD233 Protein, His Tag, Avi Tag, Recombinant Protein, KMP2247
物种: Human
宿主: HEK293 Cells
规格: 50ug, 100ug, 200ug
纯化方式: Affinity purification
纯度: >95% as determined by SDS-PAGE
内毒素水平: <1.0 EU/ug determined by the LAL method
缓冲体系: PBS, pH7.4
Uniprot: P18627
SDS-PAGE: KMP2247 SDS-PAGE image1.png
功能: Lymphocyte activation gene 3 protein: Inhibitory receptor on antigen activated T-cells (PubMed:7805750, PubMed:8647185, PubMed:20421648).
Delivers inhibitory signals upon binding to ligands, such as FGL1 (By similarity).
FGL1 constitutes a major ligand of LAG3 and is responsible for LAG3 T-cell inhibitory function (By similarity).
Following TCR engagement, LAG3 associates with CD3-TCR in the immunological synapse and directly inhibits T-cell activation (By similarity).
May inhibit antigen-specific T-cell activation in synergy with PDCD1/PD-1, possibly by acting as a coreceptor for PDCD1/PD-1 (By similarity).
Negatively regulates the proliferation, activation, effector function and homeostasis of both CD8+ and CD4+ T-cells (PubMed:7805750, PubMed:8647185, PubMed:20421648).
Also mediates immune tolerance: constitutively expressed on a subset of regulatory T-cells (Tregs) and contributes to their suppressive function (By similarity).
Also acts as a negative regulator of plasmacytoid dendritic cell (pDCs) activation (By similarity).
Binds MHC class II (MHC-II); the precise role of MHC-II-binding is however unclear (PubMed:8647185).
产品背景: Human Lymphocyte activation gene 3 protein( LAG3) is a member of immunoglobulin(Ig) superfamily. LAG3 contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. LAG3 is involved in lymphocyte activation and can bind to HLA class-II antigens. It is selectively expressed in activated T and NK cells. LAG3 has a negative regulatory function in T cells and acts as as a new marker of T cell induced B cell activation. As a soluble molecule, LAG3 activates antigen-presenting cells through MHC class II signaling. It can lead to increased antigen-specific T-cell responses in vivo. LAG-3 has higher affinity to MHC class II than CD4.
保存条件: Aliquot and store at -20℃ to -80℃. Avoid repeated freezing and thawing cycles.
运输条件: In general, the proteins are provided as lyophilized powder which are shipped at ambient temperature. They are shipped out in dry ice if supplied in liquid form.
说明: This product is for research use only.
