Outline of Final Research Achievements

Structural and functional analyses of novel lectins, CGL1 from Crassostrea gigas, GJL-1 from Gyractis japonica, and SPL-a/b from Saxidomus purpurata, were enforced. Structural analysis of CGL1 revealed its unique fold and binding pattern that have not been confirmed in known lectin families. GJL-1 and SPL-a/b also show unique characteristics as a result of the analyses.
