| description | This entry represents engulfment and cell motility protein 1 (ELMO1) from vertebrates. ELMO1 is a scaffolding component of the Elmo-Dock complex. It interacts with DOCK180, which is essential for activation of Rac GTPase-dependent biological processes. Its C-terminal pleckstrin homology (PH) domain mediates direct interaction to DOCK180 and is critical in Rac signalling []. ELMO1 also interacts with DOCK2 and plays a role in controlling DOCK2 levels and DOCK2-dependent T cell migration in primary lymphocytes [, ]. ELMO1 has been linked to invasive phenotype of cancer cells [, , ].ELMO 1-3 are orthologues of the Caenorhabditis elegans ced-12, which is required for the engulfment of dying cells and cell migration []. They are cytoplasmic adaptor proteins that interact with DOCK family guanine nucleotide exchange factors (GEFs) to promote activation of the small GTPase Rac []. ELMO proteins interact with the SH3-domain of DOCKs via an SH3-binding site to enhance the GEF activity of DOCKs. Regulatory GTPases in the Ras superfamily employ a cycle of alternating GTP binding and hydrolysis, controlled by GEFs and GTPase-activating proteins (GAPs), as essential features of their actions in cells [, ]. |
