Background

Function
CD223/LAG-3 is a 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; 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[1][2][3].

Expression
Tissue_specificity:It is mainly expressed in activated T cells and some natural killer (NK) cells.
Induction:Expression is induced by interleukin-2 (IL2) , interleukin-7 (IL7) and interleukin-12 (IL12A and IL12B) on activated T-cells -
Isoforms & Post-Translational Modification
P18627 has 2 isomers: P18627-1: 57449 Da (predicted); P18627-2: 39103 Da (predicted).
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 -
Subunit
Interacts with MHC class II (MHC-II); selectively recognizes stable complexes of peptide and MHC-II (PubMed:1692078, PubMed:7589152, PubMed:8647185, PubMed:9159144). Interacts with FGL1 (via the Fibrinogen C-terminal domain) (PubMed:30580966)
