RhoA Protein, Human (sf9, His)

The RhoA protein is a critical small GTPase that dynamically regulates multiple cellular responses by cycling between an active GTP-bound state and an inactive GDP-bound state. It mainly affects cytoskeletal organization, interacts with various effectors, and affects cytoskeletal dynamics, cell migration, and cell cycle progression. RhoA Protein, Human (sf9, His) is the recombinant human-derived RhoA protein, expressed by Sf9 insect cells , with N-His labeled tag. The total length of RhoA Protein, Human (sf9, His) is 193 a.a., with molecular weight of ~28 kDa.

RhoA Protein is a small GTPase crucial for orchestrating diverse cellular responses, cycling between an active GTP-bound state and an inactive GDP-bound state. Primarily associated with the organization of the cytoskeleton, the active form of RhoA binds to various effector proteins, influencing cellular processes such as cytoskeletal dynamics, cell migration, and cell cycle progression. It plays a pivotal role in regulating signal transduction pathways that connect plasma membrane receptors to the assembly of focal adhesions and actin stress fibers. Additionally, RhoA is indispensable for microtubule-dependent signals required for myosin contractile ring formation during cell cycle cytokinesis, contributing to cleavage furrow formation. Essential for apical junction formation in keratinocyte cell-cell adhesion, RhoA also participates in the MEMO1-RHOA-DIAPH1 signaling pathway, influencing ERBB2-dependent microtubule stabilization. It further modulates potassium channel activity, regulates guanine nucleotide exchange factors, and acts as a target for the yopT cysteine peptidase from Yersinia pestis during microbial infection.

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 500 mM NaCl, pH 7.4, 10% Glycerol. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
