CC -!- FUNCTION: V region of the variable domain of T cell receptor (TR) beta
CC chain that participates in the antigen recognition (PubMed:24600447).
CC Alpha-beta T cell receptors are antigen specific receptors which are
CC essential to the immune response and are present on the cell surface of
CC T lymphocytes. Recognize peptide-major histocompatibility (MH) (pMH)
CC complexes that are displayed by antigen presenting cells (APC), a
CC prerequisite for efficient T cell adaptive immunity against pathogens
CC (PubMed:25493333). Binding of alpha-beta TR to pMH complex initiates
CC TR-CD3 clustering on the cell surface and intracellular activation of
CC LCK that phosphorylates the ITAM motifs of CD3G, CD3D, CD3E and CD247
CC enabling the recruitment of ZAP70. In turn ZAP70 phosphorylates LAT,
CC which recruits numerous signaling molecules to form the LAT
CC signalosome. The LAT signalosome propagates signal branching to three
CC major signaling pathways, the calcium, the mitogen-activated protein
CC kinase (MAPK) kinase and the nuclear factor NF-kappa-B (NF-kB)
CC pathways, leading to the mobilization of transcription factors that are
CC critical for gene expression and essential for T cell growth and
CC differentiation (PubMed:23524462). The T cell repertoire is generated
CC in the thymus, by V-(D)-J rearrangement. This repertoire is then shaped
CC by intrathymic selection events to generate a peripheral T cell pool of
CC self-MH restricted, non-autoaggressive T cells. Post-thymic interaction
CC of alpha-beta TR with the pMH complexes shapes TR structural and
CC functional avidity (PubMed:15040585). {ECO:0000303|PubMed:15040585,
CC ECO:0000303|PubMed:23524462, ECO:0000303|PubMed:24600447,
CC ECO:0000303|PubMed:25493333}.
CC -!- SUBUNIT: Alpha-beta TR is a heterodimer composed of an alpha and beta
CC chain; disulfide-linked. The alpha-beta TR is associated with the
CC transmembrane signaling CD3 coreceptor proteins to form the TR-CD3 (TcR
CC or TCR). The assembly of alpha-beta TR heterodimers with CD3 occurs in
CC the endoplasmic reticulum where a single alpha-beta TR heterodimer
CC associates with one CD3D-CD3E heterodimer, one CD3G-CD3E heterodimer
CC and one CD247 homodimer forming a stable octomeric structure. CD3D-CD3E
CC and CD3G-CD3E heterodimers preferentially associate with TR alpha and
CC TR beta chains, respectively. The association of the CD247 homodimer is
CC the last step of TcR assembly in the endoplasmic reticulum and is
CC required for transport to the cell surface.

CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000303|PubMed:20452950}.
CC -!- POLYMORPHISM: There are several alleles. The sequence shown is that of
CC IMGT allele TRBV11-2*01. {ECO:0000305}.
