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. 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℃/-80℃. 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
Basically, we can dispatch the products out in 3-7 working days after receiving your orders. 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℃ for up to one week.

Target Background

Function
Key regulator of transforming growth factor beta (TGFB1, TGFB2 and TGFB3) that controls TGF-beta activation by maintaining it in a latent state during storage in extracellular space. Associates specifically via disulfide bonds with the Latency-associated peptide (LAP), which is the regulatory chain of TGF-beta, and regulates integrin-dependent activation of TGF-beta.
Gene References into Functions
  1. DMD gene mutations involving the hinge 3 region, actin-binding domain, and exons 45-49, as well as the LTBP4 IAAM haplotype, were not associated with age of left ventricular dysfunction onset inDuchenne muscular dystrophy. PMID: 29766838
  2. High LTBP4 expression is associated with recurrence in glioblastoma. PMID: 27270107
  3. Studied the potential role of LTBP-4 in scleroderma through clinical, in vivo and in vitro studies. Results suggest that LTBP-4 protein level is increased in plasma and skin tissue of scleroderma patients; found LTBP-4 to be a potential biomarker to differentiate systemic scleroderma (SSc) from localized scleroderma (LSc) patients. PMID: 28263294
  4. The LTBP4 VTTT allele is associated with increased risk of dilated cardiomyopathy in European Americans. LTBP4 protein with the IAAM residues bound more latent TGFbeta compared to the LTBP4 VTTT protein. PMID: 26918958
  5. Our results show that LTBP4 interacts with TGFBR2 and stabilizes TGFbeta receptors by preventing their endocytosis and lysosomal degradation in a ligand-dependent and receptor kinase activity-dependent manner. PMID: 25882708
  6. We show that corticosteroid treatment and the IAAM haplotype of the LTBP4 gene are significantly associated with prolonged ambulation in patients with Duchenne muscular dystrophy PMID: 25476005
  7. In the mdx mouse model of Duchenne muscular dystrophy, the human LTBP4 transgene exacerbated muscular dystrophy symptoms and resulted in weaker muscles with an increased inflammatory infiltrate. PMID: 25338755
  8. In Caucasians with Duchenne muscular dystrophy and LTBP4 genotype there was a protective effect on age at loss of ambulation. PMID: 25641372
  9. It recruits elastin to microfibrils via fibulin-5. PMID: 25675815
  10. LTBP4 haplotype influences age at loss of ambulation, and should be considered in the management of Duchenne muscular dystrophy patients. PMID: 23440719
  11. Latent transforming growth factor beta-binding protein 4 is downregulated in esophageal cancer via promoter methylation. PMID: 23741501
  12. Data indicate mutations of FBLN4, FBLN5, and LTBP4 in 12 probands presenting with type 1 recessive cutis laxa. PMID: 22829427
  13. the G1 and G3 domains of versican were upregulated and LTBP-4 was downregulated in breast cancer stroma PMID: 21505857
  14. The lack of LTBP4-mediated targeting in malignant mammary tumor tissues may lead to a possible modification of TGF-ss1 and BMP bioavailability and function. PMID: 21468687
  15. Meta-analysis of abdominal aortic aneurysm size and growth rates demonstrated a significant association with the LTBP4 21011A>T genotype (a 2% decrease in AAA diameter, or a 0.53 mm/year reduction in AAA growth rate, per T allele [p=0.03, p=0.01]). PMID: 19897194
  16. These data suggest that LTBP-4 functions are modified by tissue-specific expression of the two N-terminally distinct variants, which in addition exhibit significant differences in cellular processing and targeting. PMID: 20175115
  17. Extracellular matrix is an important site of deposition for LTBP-3 and LTBP-4. PMID: 16157329
  18. Our findings suggest that variations in or near the HPN and LTBP4 genes do not play a role in the susceptibility to IA in the Dutch population. PMID: 18487557
  19. Novel functions for LTBP-4 as an adhesion molecule. PMID: 18585707
  20. Mutations in LTBP4 cause a syndrome of impaired pulmonary, gastrointestinal, genitourinary, musculoskeletal, and dermal development. PMID: 19836010
