InterPro	IPR013098
Available protein structures: Pfam structures PDB RCSB PDB; PDBe; PDBj PDBsum structure summary

I-set domains are found in several cell adhesion molecules, including vascular (VCAM), intercellular (ICAM), neural (NCAM) and mucosal addressin (MADCAM) cell adhesion molecules, as well as junction adhesion molecules (JAM). I-set domains are also present in several other diverse protein families, including several tyrosine-protein kinase receptors, the hemolymph protein hemolin, the muscle proteins titin, telokin, and twitchin, the neuronal adhesion molecule axonin-1, and the signalling molecule semaphorin 4D that is involved in axonal guidance, immune function and angiogenesis.
