    Summary · context
    Using GST pull-down assays, surface plasmon resonance (SPR), isothermal titration calorimetry (ITC), and other methods, we found that the intracellular segment residues 522-526 of ICAM-1 bind directly to the phosphotyrosine interaction domain (PID) of JNK interacting protein 1 (JIP1; residues 586-593).
