Rho GDP-dissociation inhibitor 1 (ARHGDIA), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2-204aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal GST-tagged. Target Protein Sequence: AEQEPTAEQL AQIAAENEED EHSVNYKPPA QKSIQEIQEL DKDDESLRKY KEALLGRVAV SADPNVPNVV VTGLTLVCSS APGPLELDLT GDLESFKKQS FVLKEGVEYR IKISFRVNRE IVSGMKYIQH TYRKGVKIDK TDYMVGSYGP RAEEYEFLTP VEEAPKGMLA RGSYSIKSRF TDDDKTDHLS WEWNLTIKKD WKD. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Controls Rho proteins homeostasis. Regulates the GDP/GTP exchange reaction of the Rho proteins by inhibiting the dissociation of GDP from th, and the subsequent binding of GTP to th. Retains Rho proteins such as CDC42, RAC1 and RHOA in an inactive cytosolic pool, regulating their stability and protecting th from degradation. Actively involved in the recycling and distribution of activated Rho GTPases in the cell, mediates extraction from mbranes of both inactive and activated molecules due its exceptionally high affinity for prenylated forms. Through the modulation of Rho proteins, may play a role in cell motility regulation. In glioma cells, inhibits cell migration and invasion by mediating the signals of SA5A and PLXNB3 that lead to inactivation of RAC1.

In glioma cells, inhibits cell migration and invasion by mediating the signals of SEMA5A and PLXNB3 that lead to inactivation of RAC1.
