Polyclonal Sheep Affinity Purified E B
IGSF3 (immunoglobulin superfamily member 3; also EWI-3) is a member of the EWI subfamily of the Ig-Superfamily of molecules. It is a type I transmembrane protein that likely exists as a homodimer in kidney and lung. The mature molecule is 1195 amino acids (aa) in length, and contains an extended 1127 aa extracellular domain (ECD) (aa 20-1146). There are seven ECD V-type Ig-like domains, the second of which exhibits a characteristic Glu-Trp-Ile motif. There are at least two potential splice variants. One shows a truncation after Pro833; a second shows a deletion of aa 408-427. Over aa 20-1125, human IGSF3 shares 92% aa identity with mouse IGSF3.
Catalog #I7502-95
