The structures of Vβ17 TCR β chains. (A,B) Representative (2Fo − Fc) electron density maps, contoured at 1.0σ, of the CDR3 regions of Vβ17C5–1YS (A) and Vβ17SF4 (B). (C,D) Ribbon diagram of the Vβ17C5–1YS homodimers in two possible associations. (C) Dimerization via Vβ domains; (D) dimerization via Cβ domains. The TCR Vβ, Cβ and CDR loops are labeled.
