Evasin-3 is a highly selective chemokine-binding protein isolated from tick saliva. The cDNA of tick Evasin-3 encodes an 86 amino acid (aa) precursor, which includes a 20 aa signal peptide and a 66 aa mature protein (1). Ticks are blood sucking parasites that secrete a wide variety of immunomodulatory proteins to evade the host immune response. The saliva isolated from Ticks has shown to contain chemokine neutralization activity. These proteins have been identified as chemokine binding proteins (CHPBs) that were termed as Evasins (1,2.3). Evasin-3 belongs to a new class of chemokine binding proteins in that it shows high affinity binding to a very limited set of chemokines, including CXCL8 and CXCL1. Since it is very small molecule Evasin-3 may be therapeutically useful as novel anti-inflammatory agent.
