Figure 1. A schematic drawing of a T cell αβ receptor and
its binding site. On the left we show the arrangements of the V
and C domains and the helices that attach the receptor to the
cell surface. On the right we show a schematic drawing of the T
cell binding site. The hypervariable regions are labelled α1,
α2, α3, β1, β2 and β3. They are attached to strands of
β-sheet that are approximately perpendicular to the page and
are shown as open squares.
