Engulfment and cell motility protein 1 is a protein that in humans is encoded by the ELMO1 gene. [5] [6] ELMO1 is located on chromosome number seven in humans and is located on chromosome number thirteen in mice.
The human engulfment and cell motility protein 1, ELMO1, is 720 residues in length. The protein contains the following three domains:
ELMO1 also has a pro-rich motif at the extreme C terminus. Secondary structure analysis has predicted that there are alpha-helical regions at both the N and C-terminus. [7]
The structure of the pleckstrin homology domain of ELMO1 has been determine by X-ray crystallography. [7]
The protein encoded by this gene interacts with the dedicator of cyto-kinesis 1 protein to promote phagocytosis and effect cell shape changes. Similarity to a C. elegans protein suggests that this protein may function in apoptosis and in cell migration. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. [6]
ELMO1 has been shown to interact with Dock180 [5] [8] and HCK. ELMO1 directly interacts with the SH3 domain of HCK. The association between ELMO1 and HCK is dependent on polyproline interactions. [9]
When ELMO1 is complexed with DOCK180, Rac GTPase-dependent biological processes are activated. The pH domain of ELMO1 functions in trans to stabilize DOCK180 and make it resistant to degradation. When ELMO1 binds to DOCK180 it relieves the steric inhibition of DOCK180 which then activates the Rac GTPase. The pro-rich motif of the C terminus on ELMO1 is essential for the binding of ELMO1 to the SH3 domain at the N terminus of DOCK180. [7] The complex of ELMO1 and DOCK180 act as a regulator of Rac during development of a cell and cell migration. Mutation of both interaction sites for DOCK180 on ELMO1 will lead to the disruption of the ELMO1-DOCK180 complex. ELMO1 complexed with both DOCK180 and CrkII leads to maximal efficiency of phagocytosis in the cell. This complex of molecules happens upstream of Rac during phagocytosis. [5]

Dedicator of cytokinesis protein 1 (Dock1), also (DOCK180), is a large protein encoded in the human by the DOCK1 gene, involved in intracellular signalling networks. It is the mammalian ortholog of the C. elegans protein CED-5 and belongs to the DOCK family of guanine nucleotide exchange factors (GEFs).

ELMO is a family of related proteins 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.
CED-12 is a cytoplasmic, PH-domain containing adaptor protein found in Caenorhabditis elegans and Drosophila melanogaster. CED-12 is a homolog to the ELMO protein found in mammals. This protein is involved in Rac-GTPase activation, apoptotic cell phagocytosis, cell migration, and cytoskeletal rearrangements.
DHR1, also known as CZH1 or Docker1, is a protein domain of approximately 200–250 amino acids that is present in the DOCK family of signalling proteins. This domain binds phospholipids and so may assist in recruitment to cellular membranes. There is evidence that this domain may also mediate protein–protein interactions.
DHR2, also known as CZH2 or Docker2, is a protein domain of approximately 450-550 amino acids that is present in the DOCK family of proteins. This domain functions as a guanine nucleotide exchange factor (GEF) domain for small G proteins of the Rho family. DHR2 domains bear no significant similarity to the well described DH domain present in other RhoGEFs such as Vav, P-Rex and TRIO. Indeed, the most divergent mammalian DHR2 domains share only 16-17% sequence similarity.
