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.
and FAQs
Protein FAQs
Storage Condition Store at -20°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

(From Uniprot)
Major structural component of sperm fibrous sheath. Plays a role in sperm motility.
Gene References into Functions
  1. High AKAP4 expression is associated with reduced sperm motility. PMID: 29581387
  2. A significant association was found between AKAP4 gene expression and metastasis (P-value: 0.045), expression of the CTAG1B (NY-ESO-1) gene was not observed in our cases. PMID: 29480665
  3. the physiological role of the negative crosstalk between the cAMP/PKA/AKAP4 and the PKC/ERK1/2 pathways is to regulate capacitation and acrosome reaction. PMID: 27901058
  4. AKAP4 role in the proliferation and metastasis of thyroid cancer.AKAP4 is highly expressed in thyroid cancer. PMID: 27983916
  5. AKAP4 appears to be a novel Colorectal cancer-associated antigen with a potential for developing as a new clinical therapeutic target PMID: 26590805
  6. AKAP4 is a highly accurate biomarker for the detection of early stage lung cancer. PMID: 26160834
  7. SP17/AKAP4/PTTG1 are expressed in both human NSCLC cell lines and primary tumors and can elicit an immunogenic response in lung cancer patients. PMID: 25739119
  8. The putative role of AKAP4 in early tumorigenesis is implicated as a biomarker and immunotherapeutic target for cervical cancer. PMID: 23478221
  9. Ablation of AKAP4 protein caused significant inhibition in cellular proliferation, colony-forming ability, migration and invasion ability of tumor cells. PMID: 23764900
  10. data suggests that AKAP4 may be used as serum based diagnostic test for an early detection and diagnosis of breast cancer and may be a potential target for immunotherapeutic use PMID: 23451156
  11. We demonstrate the aberrant expression of AKAP-4 in prostate cancer, which will potentially be developed as a biomarker in prostate cancer. PMID: 21520158
  12. AKAP4 is a novel target for protein S-nitrosylation in spermatozoa. PMID: 17683036
  13. Role of AKAP4 in sperm motility is unclear, vut absent or weak AKAP4-labelling is associated with absent or weak sperm. motility. PMID: 17712481
