Recombinant Human ELMO1, N-His

Introduction

Recombinant Human ELMO1, also known as Engulfment and Cell Motility protein 1, is a protein that plays a crucial role in cell migration and phagocytosis. It is a member of the ELMO protein family, which is involved in regulating the activity of the small GTPase Rac during cell movement. Recombinant Human ELMO1 is a valuable tool in scientific research and has potential applications in various fields, including immunology and cancer research.

Structure of Recombinant Human ELMO1

Recombinant Human ELMO1 is a 98 kDa protein composed of 884 amino acids. It contains several domains, including an N-terminal ELMO domain, a PH domain, and a C-terminal SH3 domain. The ELMO domain is responsible for binding to the small GTPase Rac, while the PH domain is involved in membrane localization. The SH3 domain is important for protein-protein interactions and is responsible for binding to other signaling proteins.

Activity of Recombinant Human ELMO1

Recombinant Human ELMO1 plays a critical role in cell migration and phagocytosis by regulating the activity of Rac. Rac is a small GTPase that controls actin polymerization and cytoskeletal rearrangement, which are essential processes for cell movement. By binding to Rac, Recombinant Human ELMO1 activates Rac and promotes its localization to the leading edge of migrating cells. This results in the formation of lamellipodia, which are thin, sheet-like protrusions that facilitate cell movement.

In addition to its role in cell migration, Recombinant Human ELMO1 also plays a crucial role in phagocytosis, the process by which cells engulf and digest foreign particles. It promotes the formation of phagocytic cups, which are cup-shaped structures that surround the target particle and facilitate its uptake by the cell. Recombinant Human ELMO1 also interacts with other proteins involved in phagocytosis, such as DOCK1 and CRKII, to regulate the activity of Rac and promote efficient phagocytosis.

Applications of Recombinant Human ELMO1

Recombinant Human ELMO1 has a wide range of applications in scientific research. Its role in cell migration and phagocytosis makes it a valuable tool for studying these processes. It can be used to investigate the mechanisms of cell movement and to identify potential therapeutic targets for diseases that involve abnormal cell migration, such as cancer metastasis.

In immunology research, Recombinant Human ELMO1 can be used to study the role of phagocytosis in the immune response. It can also be used to investigate the signaling pathways involved in phagocytosis and to identify potential therapeutic targets for diseases that involve impaired phagocytosis, such as autoimmune disorders.

Furthermore, Recombinant Human ELMO1 has potential applications in drug discovery. As it plays a critical role in cell migration, it can be targeted for the development of drugs that inhibit or promote cell movement, depending on the desired outcome. This could have implications for various diseases, including cancer, where inhibiting cell migration could prevent metastasis, and promoting cell migration could aid in tissue repair.

Conclusion

Recombinant Human ELMO1 is a crucial protein involved in cell migration and phagocytosis. Its structure and activity make it a valuable tool for scientific research, with potential applications in various fields. Further research on Recombinant Human ELMO1 could lead to a better understanding of the mechanisms of cell movement and phagocytosis, as well as the development of novel therapeutic strategies for diseases involving these processes.
