Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Microtubule plus-end tracking protein that promotes the stabilization of dynamic microtubules. Involved in the nucleation of noncentrosomal microtubules originating from the trans-Golgi network (TGN). Required for the polarization of the cytoplasmic microtubule arrays in migrating cells towards the leading edge of the cell. May act at the cell cortex to enhance the frequency of rescue of depolymerizing microtubules by attaching their plus-ends to cortical platforms composed of ERC1 and PHLDB2. This cortical microtubule stabilizing activity is regulated at least in part by phosphatidylinositol 3-kinase signaling. Also performs a similar stabilizing function at the kinetochore which is essential for the bipolar alignment of chromosomes on the mitotic spindle. Acts as a mediator of ERBB2-dependent stabilization of microtubules at the cell cortex.

  1. CLASP2 is involved in the epithelial-mesenchymal transition and progression of bladder urothelial cancer. Simultaneous urine-based detection of CLASP2 and E-cadherin mRNA can efficiently discriminate patients with or without 2-years progression after transurethral resection of the bladder tumor. PMID: 28166762
  2. These findings reveal a new role for Clasp2 in governing keratinocyte undifferentiated features. PMID: 28069833
  3. Prickle1 localized to the membrane through its farnesyl moiety, and the membrane localization was necessary for Prickle1 to regulate migration, to bind to CLASPs and LL5beta, and to promote microtubule targeting of focal adhesions. PMID: 27378169
  4. this study shows that GSK3-mediated phosphorylation of CLASP2alpha largely abolishes CLASP2alpha-microtubule association in metaphase thus contributing to correct chromosome dynamics PMID: 28232523

  7. Propose that CLASPs couple microtubule organization, vesicle transport and cell interactions with the ECM, establishing a local secretion pathway that facilitates focal adhesion turnover by severing cell-matrix connections. PMID: 24859005
  8. Results suggest a previously unidentified role for the scaffolding protein 4.1R in locally controlling CLASP2 behavior, CLASP2 cortical platform turnover and GSK3 activity, enabling correct MT organization and dynamics essential for cell polarity. PMID: 23943871
  9. The epiblast epithelial status was maintained by anchoring microtubules to the basal cortex via CLIP2, a microtubule plus-end tracking protein, and Dystroglycan, a transmembrane protein that bridges the cytoskeleton and basement membrane (BM). PMID: 23940118
  10. Overexpression of human CLASP2 in mouse neurons caused the formation of multiple axons, enhanced dendritic branching, & Golgi condensation. These morphogenetic changes led to significant functional alterations in synaptic transmission. PMID: 23035100
  11. propose that Cdk1 and Plk1 mediate a fine CLASP2 "phospho-switch" that temporally regulates kinetochore-microtubule attachment stability PMID: 23045552
  12. Data show that CENP-E-mediated traction forces on misaligned chromosomes are responsible for the irreversible loss of spindle-pole integrity in CLASP1/2-depleted cells. PMID: 22307330

  14. Data report that NEK1 and CLASP2 colocalize with FEZ1 in a perinuclear region in mammalian cells, and observed that coiled-coil interactions occur between FEZ1/CLASP2 and FEZ1/NEK1 in vitro. PMID: 19924516
  15. propose that CLASP1 and CLASP2 can mediate interactions between microtubule plus ends and the cell cortex and act as local rescue factors, possibly through forming a complex with EB1 at microtubule tips PMID: 15631994
  16. These results demonstrate the striking difference of the microtubule cytoskeleton in the lamella as compared with the cell body and provide the first direct observation of subcellular regulation of a microtubule-associated protein in migrating cells. PMID: 15955847
  17. CLASPs provide apparent stabilization of microtubules by locally reducing the amplitude of growth/shortening episodes at the microtubule ends. PMID: 16866869
  18. Together, our data support that the partial redundancy of CLASPs during mitosis acts as a possible mechanism to prevent aneuploidy in mammals. PMID: 16914514
  19. GSK3beta phosphorylation modulates CLASP-microtubule association and lamella microtubule attachment. PMID: 19289791
  20. A role for microtubules that form at the Golgi membranes is identified in a manner dependent on the microtubule regulators CLASPs. PMID: 19701196
