Target Details

Target Function The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. That Rab is involved in the process of endocytosis and is an essential rate-limiting regulator of the fast recycling pathway back to the plasma membrane. During cytokinesis, required for the postfurrowing terminal steps, namely for intercellular bridge stability and abscission, possibly by controlling phosphatidylinositol 4,5-bis phosphate (PIP2) and SEPT2 localization at the intercellular bridge. May indirectly regulate neurite outgrowth. Together with TBC1D13 may be involved in regulation of insulin-induced glucose transporter SLC2A4/GLUT4 translocation to the plasma membrane in adipocytes.

Gene Functions References

  1. A RAB35-p85/PI3K axis controls oscillatory apical protrusions required for efficient chemotactic migration. PMID: 29662076
  2. The results provide evidence that MICAL1 plays an essential role in the activation of ROS/Akt signaling and cell invasive phenotype and identify a novel link between RAB35 and MICAL1 in regulating breast cancer cell invasion. PMID: 27430308
  3. The involvement of Rab35 in diverse and apparently unrelated cellular functions can be explained by the central role of this GTPase in regulating phosphoinositides and F-actin, both on endosomes and at the plasma membrane[review]. PMID: 27329675
  4. Data suggest that Rab35, interacting with TBC1D10A, functions in vascular endothelial cells as a negative regulator of histamine-evoked, Ca2+-dependent Weibel-Palade body exocytosis, most likely acting through the downstream effectors ACAP2 and Arf6. (Rab35 = rab GTP-binding protein 53; TBC1D10A = TBC1 domain family member 10A; ACAP2 = centaurin beta2; Arf6 = ADP-ribosylation factor 6) PMID: 28566286
  5. Short-term EGF stimulation if of lung tumor cells can increase the interaction between RUSC2 and GIT2, prolonged stimulation leads to a decrease of their interaction through activating Rab35. PMID: 27238570
  6. Here the authors report that EspG interacts specifically with the small GTPases ARF6 and Rab35 during infection. PMID: 27261256
  7. Authors propose that the precise spatial and temporal activation of Rab35 acts as a major switch for OCRL recruitment on newborn endosomes, post-scission PtdIns(4,5)P2 hydrolysis, and subsequent endosomal trafficking. PMID: 26725203
  8. Rab35 serves as a clathrin-mediated endocytosis detector. Loss of Rab35 input leads to elevated Arf6-GTP and shifts the sorting of clathrin-independent endocytosis cargo proteins to lysosomes. PMID: 25988331
  9. the activation-inactivation cycles of Rab35 and ARF6 are required for the uptake of zymosan and that ACAP2 is an important component that links Rab35/ARF6 signaling during phagocytosis of zymosan. PMID: 26229970
  10. Two somatic RAB35 mutations found in human tumors generate alleles that constitutively activate PI3K/AKT signaling, suppress apoptosis, and transform cells in a PI3K-dependent manner. PMID: 26338797
  11. mutual regulation with arf6 of cell adhesion and migration PMID: 23264734
  12. Rab35 acts as a downstream target of Dvl2 and mediates cell migration. PMID: 23353182
  13. Activated ARF6 reduces Rab35 loading into the endocytic pathway. PMID: 22226746
  14. whereas connecdenn 1 and 2 activate Rab35 for endosomal trafficking, connecdenn 3 uniquely activates Rab35 for its role in actin regulation PMID: 22072793
  15. analysis of DENND1B-S complexed with its substrate Rab35 PMID: 22065758
  16. the phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2) 5-phosphatase OCRL, which is mutated in Lowe syndrome patients, is an effector of the Rab35 GTPase in cytokinesis abscission PMID: 21706022
  17. A Small Ras-like GTPase protein Ray was indicated to modulate p53 transcriptional activity of PRPK. PMID: 16600182
  18. localized to the plasma membrane and endocytic compartments and controls a fast endocytic recycling pathway; plays an essential role during the terminal steps of cytokinesis PMID: 16950109
  19. EPI64C and Rab35 regulate a recycling pathway in T cells and contribute to immunological synapse formation, most likely by participating in TCR transport to the immunological synapse PMID: 18450757
  20. study found that Rab35 regulates the assembly of actin filaments in filopodia formation; effect was mediated by the actin-bundling protein fascin, which directly associated with active Rab35 PMID: 19729655

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
