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 FN-plug domain found near the central region of Teneurins 1 to 4, a group of proteins involved in development and function of the nervous system [1-3].

The Antibiotic-Binding-Like Domain (ABD) is a conserved structural motif identified in the teneurin family of proteins, characterized by its resemblance to bacterial proteins known to bind small-molecule antibiotics such as bleomycin and zorbamycin. In the crystal structure of chicken Ten2, the ABD comprises approximately 120 residues and is positioned immediately downstream of the shell exit site. Structural homology analyses reveal similarities between the ABD of chicken Ten2 and antibiotic-binding proteins found in bacteria. These bacterial proteins confer resistance to antibiotics by sequestering them, thereby preventing their activation by oxygen. The ABD of teneurins wraps around a long helix that leads into the most C-terminal domain, known as the ToxGHH domain.	Domain
