GeneCards Summary for TRA Gene
TRA (T Cell Receptor Alpha Locus) is a Protein Coding gene. Diseases associated with TRA include Precursor T-Cell Acute Lymphoblastic Leukemia and T-Cell Receptor-Alpha/Beta Deficiency. Among its related pathways are Transcription_NF-kB signaling pathway and G-protein signaling N-RAS regulation pathway.
UniProtKB/Swiss-Prot Summary for TRA Gene
The alpha chain of TRAV27*01J42*01C*01/TRBV19*01J2S7*01C*02 alpha-beta T cell receptor (TR) clonotype that is specific for HLA-A*02:01-restricted M/matrix protein 1 immunodominant epitope GILGFVFTL of influenza A virus (IAV). Classified as a public TR clonotype, it is preferentially selected in effector memory CD8-positive T cells among multiple HLA-A*02:01 carriers and confers long-lived immunity against IAV infection. Can cross-recognize sporadically emerging IAV variants by molecular mimicry, inducing immunity toward different influenza strains (PubMed:1833769, PubMed:7807026, PubMed:29997621, PubMed:27036003, PubMed:12796775, PubMed:18275829). Antigen recognition initiates TR-CD3 clustering on the cell surface and intracellular activation of LCK that phosphorylates the ITAM motifs of CD3G, CD3D, CD3E and CD247 enabling the recruitment of ZAP70. In turn, ZAP70 phosphorylates LAT, which recruits numerous signaling molecules to form the LAT signalosome. The LAT signalosome propagates signal branching to three major signaling pathways, the calcium, the mitogen-activated protein kinase (MAPK) kinase and the nuclear factor NF-kappa-B (NF-kB) pathways, leading to the mobilization of transcription factors that are critical for gene expression and essential for T cell differentiation into effector/memory T cells (By similarity).
