What is the role of ELMO1 gene in cell migration?
ELMO proteins are also known to regulate actin cytoskeleton reorganization through activation of the small GTPbinding protein Rac via the ELMO-Dock180 complex. In mammalian cells, ELMO1 interacts with Dock180 as a component of the CrkII/Dock180/Rac pathway responsible for phagocytosis and cell migration.  We also show that Hck and ELMO1 interact in intact cells and that ELMO1 is heavily tyrosine-phosphorylated in cells that co-express Hck, suggesting that it is a substrate of Hck.The ELMO1/DOCK180 complex then forms a guanine nucleotide exchange factor for Rac1, regulating its activation during cell migration in different biological systems. Rac activation by the ELMO.Dock180 complex at discrete intracellular locations is mediated by the N-terminal 330 amino acids of ELMO1 rather than generalized Rac activation plays a role in cell migration.
