A basic protein cytolysin previously isolated from the Caribbean sea anemone Stichodactyla helianthus was shown by CM cellulose chromatography to consist of four isotoxins possessing different N-terminal amino acid sequences. These are designated as toxins I-IV in order of increasing isoelectric

The RNase gene superfamily combines functionally divergent proteins which share statistically significant sequence similarity. Known members assigned to this family include secretory and nonsecretory RNases; angiogenin; eosinophil cationic protein; eosinophil-derived neurotoxin; sialic-acid binding

Neutrophil attractant/activation protein-1 (NAP-1 [interleukin-8]) is an 8,400 D protein that is a chemoattractant and granule release stimulus for neutrophils. NAP-1 was first purified from culture fluids of lipopolysaccharide-stimulated human blood mononuclear leukocytes. It was subsequently
