==Eosinophil-derived Neurotoxin (EDN) - Sulphate Complex==
-
Eosinophil-derived neurotoxin (EDN), a basic ribonuclease found in the, large specific granules of eosinophils, belongs to the pancreatic RNase A, family. Although its physiological function is still unclear, it has been, shown that EDN is a neurotoxin capable of inducing the Gordon phenomenon, in rabbits. EDN is also a potent helminthotoxin and can mediate antiviral, activity of eosinophils against isolated virions of the respiratory, syncytial virus. EDN is a catalytically efficient RNase sharing similar, substrate specificity with pancreatic RNase A with its ribonucleolytic, activity being absolutely essential for its neurotoxic, helminthotoxic, and antiviral activities. The crystal structure of recombinant human EDN, in the unliganded form has been determined previously (Mosimann, S. ... [[http://ispc.weizmann.ac.il/pmbin/getpm?11154698 (full description)]]

[https://www.uniprot.org/uniprot/RNAS2_HUMAN RNAS2_HUMAN] This is a non-secretory ribonuclease. It is a pyrimidine specific nuclease with a slight preference for U. Cytotoxin and helminthotoxin. Selectively chemotactic for dendritic cells. Possesses a wide variety of biological activities.<ref>PMID:3458170</ref> <ref>PMID:12578357</ref>
