The D-galactoside binding lectin purified from sea urchin (Anthocidaris crassispina) eggs exists as a disulphide-linked homodimer of two subunits; the dimeric form is essential for hemagglutination activity [1]. The sea urchin egg lectin (SUEL) forms a new class of lectins that binds D-galactoside and L-rhamnose, with preference for L-rhamnose [1,2].	Domain

This entry represents the N-terminal Ig-like domain of unc-5 family members. The unc-5 family consists of netrin receptors that play a crucial role in axon guidance and neuronal development. These receptors mediate axon repulsion of neuronal growth cones in the developing nervous system upon binding with netrin ligands. They are involved in various processes such as cell-cell adhesion, cell migration, and apoptosis. The family members also function as dependence receptors, inducing apoptosis when not associated with netrin ligands. Some members are involved in vascular branching regulation during angiogenesis and interact with other proteins like DCC and FLRTs to modulate their functions. The unc-5 family is essential for proper neuronal network formation and maintenance.	Domain
