Tor protein architecture. Tor protein domain architecture is highly conserved throughout the fungal kingdom. The N-terminal HEAT repeats (blue), the FAT (green) and the FATC (purple) domains participate in protein-protein scaffolding thereby facilitating complex interactions. The FRB domain (yellow) is a highly conserved 100 amino acid sequence necessary for rapamycin interaction. The kinase domain (orange) phosphorylates protein substrates.
