One Relationship between a Galectin and a Biological Phenomenon Every galectin people may get irritated by the difficulty in assigning a principal biological role to his/her galectin. Though the first step of galectin action at a molecular level, that is, the specific recognition of a certain glycoconjugate, is a simple process, biological phenomena at cellular level triggered by the first step are too diverse. The same galectin species seems to participate in development, differentiation, mor-
