Recombinant Human EHD1 Protein, N-His

Introduction to Recombinant Human EHD1 Protein

Recombinant Human EHD1 Protein is a type of protein that is synthesized in a laboratory by combining genetic material from different sources. This protein is a member of the EHD protein family, which plays a crucial role in regulating membrane trafficking and endocytic recycling. EHD1 is a highly conserved protein, meaning that it is found in many different species and has a similar structure and function across these species.

Structure of Recombinant Human EHD1 Protein

Recombinant Human EHD1 Protein is composed of 548 amino acids and has a molecular weight of approximately 62 kDa. It is made up of four domains: the N-terminal domain, the central coiled-coil domain, the nucleotide-binding domain, and the C-terminal domain. These domains work together to facilitate the protein’s function in membrane trafficking.

The N-terminal domain of EHD1 is responsible for binding to membranes and is essential for the protein’s localization to the endocytic recycling compartment. The central coiled-coil domain is responsible for protein-protein interactions, allowing EHD1 to interact with other proteins involved in membrane trafficking. The nucleotide-binding domain is responsible for binding to ATP, which is necessary for the protein’s activity. Finally, the C-terminal domain is involved in the regulation of EHD1’s function.

Activity of Recombinant Human EHD1 Protein

The main activity of Recombinant Human EHD1 Protein is its role in regulating membrane trafficking and endocytic recycling. This process involves the transport of proteins and other molecules from the cell surface to the interior of the cell and vice versa. EHD1 is specifically involved in the recycling of endocytosed receptors, which are proteins that bind to specific molecules and bring them into the cell.

EHD1 achieves this by forming a complex with other proteins, such as Rab11 and EHBP1, which are involved in the regulation of endocytic recycling. This complex helps to sort and transport endocytosed receptors back to the cell surface, allowing them to continue their function in signaling and other cellular processes.

In addition to its role in membrane trafficking, EHD1 has also been shown to play a role in other cellular processes, such as cell migration, cell division, and maintenance of the cell’s cytoskeleton. It achieves this by interacting with other proteins and regulating their activity.

Application of Recombinant Human EHD1 Protein

Recombinant Human EHD1 Protein has many potential applications in both research and medicine. Its role in regulating membrane trafficking and endocytic recycling makes it an essential protein for studying various cellular processes. It can also be used as a tool in drug discovery, as it is involved in the transport of various receptors that are targets for many diseases.

Furthermore, mutations in the gene encoding EHD1 have been linked to various diseases, including cancer, Alzheimer’s disease, and cardiovascular disease. Therefore, understanding the structure and function of EHD1 could provide valuable insights into these diseases and potentially lead to the development of new therapies.

In conclusion, Recombinant Human EHD1 Protein is a crucial protein involved in regulating membrane trafficking and endocytic recycling. Its structure and activity make it an essential protein for studying various cellular processes, and its potential applications in research and medicine make it a valuable tool for drug discovery and disease research.
