Background

  • Function

    LAT is required for TCR (T-cell antigen receptor)- and pre-TCR-mediated signaling, both in mature T-cells and during their development. Involved in FCGR3 (low affinity immunoglobulin gamma Fc region receptor III)-mediated signaling in natural killer cells and FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. Couples activation of these receptors and their associated kinases with distal intracellular events such as mobilization of intracellular calcium stores, PKC activation, MAPK activation or cytoskeletal reorganization through the recruitment of PLCG1, GRB2, GRAP2, and other signaling molecules[1][2].

  • Subcellular Localization

    Cell membrane; Single-pass type III membrane protein

  • Expression


    Tissue_specificity:It is expressed in the thymus, T cells, NK cells, and mast cells, with lower expression levels in the spleen. It is present in T cells but not in B cells (at the protein level) .

  • Isoforms & Post-Translational Modification

    O43561 has 5 isomers: O43561-1: 27930 Da (predicted); O43561-2: 24985 Da (predicted); O43561-3: 28568 Da (predicted); O43561-4: 24829 Da (predicted); O43561-5: 27774 Da (predicted).
    Phosphorylated on tyrosines by ZAP70 upon TCR activation, or by SYK upon other immunoreceptor activation; which leads to the recruitment of multiple signaling molecules. Is one of the most prominently tyrosine-phosphorylated proteins detected following TCR engagement. May be dephosphorylated by PTPRJ. Phosphorylated by ITK leading to the recruitment of VAV1 to LAT-containing complexes;Palmitoylation of Cys-26 and Cys-29 is required for raft targeting and efficient phosphorylation;'Lys-63'-linked ubiquitinated by TRAF6

  • Subunit

    When phosphorylated, interacts directly with the PIK3R1 subunit of phosphoinositide 3-kinase and the SH2 domains of GRB2, GRAP, GRAP2, PLCG1 and PLCG2. Interacts indirectly with CBL, SOS, VAV, and LCP2. Interacts with SHB, SKAP2 and CLNK (By similarity). Interacts with FCGR1A. Interacts with GRB2, PLCG1 and THEMIS upon TCR activation in thymocytes (By similarity). Interacts with THEMIS2 (By similarity)
