MHC2 pathway components. A schematic of a TCR-MHC2-CD4 complex is shown in (A). The intra-cellular tails of the CD4.1 and CD4.2 co-receptor chains are shown in (B) and (C), aligned to the orthologous sequences from T. rubripes. The locations of conserved CxC Lck-interaction motifs (black squares) and arginine/lysine-rich regions (blue line) within the intra-cellular tails are indicated
