ELMO (Engulfment and Cell Motility) is a family of related proteins (~82 kDa) involved in intracellular signalling networks. These proteins have no intrinsic catalytic activity and instead function as adaptors which can regulate the activity of other proteins through their ability to mediate protein-protein interactions. This family contains members in all animals. In humans there are three paralogous isoforms: * ELMO1 * ELMO2 * ELMO3
