SUEL-Related Lectins, a Lectin Family Widely Distributed throughout Organisms

Abstract

Glycan-binding proteins are categorized into two groups, lectins and sulfated glycosaminoglycan-binding proteins. SUEL-related lectins are members of a superfamily of proteins containing a carbohydrate-recognition domain (CRD), which is structurally similar to sea urchin egg lectin (SUEL). Here I review the structure and function of this family of proteins.
