ABSTRACT:
Proteins useful as sphingomyelin detecting probes, which specifically recognize sphingomyelin and have low cytotoxicity. The proteins of the present invention may be obtained by deletion of between about 110 to 170 amino acid residues from the N terminal or C terminal of earthworm toxin Lysenin 1. Kits for detecting sphingomyelin are also disclosed.
