Description of Recombinant Human ARHGDIA Protein, N-His

Introduction to Recombinant Human ARHGDIA Protein

Recombinant Human ARHGDIA Protein, also known as Rho GDP-dissociation inhibitor 1 (RhoGDI1), is a protein that plays a crucial role in regulating the activity of Rho GTPases. These proteins are important for various cellular processes, including cell growth, movement, and differentiation. The ARHGDIA gene is located on chromosome 17 and codes for a 204 amino acid protein with a molecular weight of approximately 23 kDa.

Structure of Recombinant Human ARHGDIA Protein

The structure of Recombinant Human ARHGDIA Protein consists of three distinct domains: the N-terminal domain, the middle domain, and the C-terminal domain. The N-terminal domain is responsible for binding to Rho GTPases, while the middle domain regulates the activity of the protein. The C-terminal domain is involved in the interaction with other proteins and is crucial for the proper functioning of ARHGDIA.

The N-terminal domain of ARHGDIA contains a hydrophobic pocket that binds to the lipid moiety of Rho GTPases, thereby inhibiting their activity. The middle domain is composed of two alpha helices and a beta sheet, which form a “claw-like” structure that interacts with the N-terminal domain. The C-terminal domain contains a conserved sequence that is essential for the binding of ARHGDIA to Rho GTPases.

Activity of Recombinant Human ARHGDIA Protein

Recombinant Human ARHGDIA Protein acts as a negative regulator of Rho GTPases by inhibiting their activity. Rho GTPases are molecular switches that cycle between an active GTP-bound state and an inactive GDP-bound state. These proteins play a crucial role in various cellular processes, including cell migration, adhesion, and cytoskeletal organization.

ARHGDIA binds to the lipid moiety of Rho GTPases, thereby preventing their activation by guanine nucleotide exchange factors (GEFs). GEFs promote the exchange of GDP for GTP, which leads to the activation of Rho GTPases. By inhibiting this process, ARHGDIA effectively blocks the activity of Rho GTPases and regulates their function in the cell.
