Exodus-2 has a unique 36 (murine) or 37 (human) amino acid carboxyl-terminal extension not seen in other chemokines. Exodus-2 selectively stimulates the chemotaxis of adult T-lymphocytes and is expressed preferentially in lymph node tissue. Exodus-2 is critical for adult T-cell adhesion to high endothelial venules in lymph nodes, a rate-limiting step for T cell trafficking through nodal tissue.
