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
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

The recombinant Human TPM3 protein is produced by constructing the recombinant plasmid encoding the Human TPM3 protein (2-285aa), transforming recombinant plasmid into e.coli cells, screening the positive e.coli cells and culturing them, and inducing the protein expression. The protein is equipped with a N-terminal GST tag. Following expression, the recombinant TPM3 protein is isolated and purified from the cell lysate using affinity purification. Denaturing SDS-PAGE is then employed to resolve the resulting recombinant Human TPM3 protein. Its purity is greater than 85%.

Target Background

Function
Binds to actin filaments in muscle and non-muscle cells. Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments.
Gene References into Functions
  1. Analysis of the residual, resected tumor identified a chromoplectic TPM3-ALK rearrangement that involved many other known oncogenes and was confirmed by rtPCR. PMID: 27742657
  2. expression levels of tropomyosin 3 (TPM3) were higher in stage III ESCC tissue compared with stage I (P<0.05). The findings of the present study identified twelve proteins, which are closely associated with ESCC invasion and metastasis, apoptosis and cell signal transduction. PMID: 28138712
  3. Dominant mutations in TPM3, encoding alpha-tropomyosinslow, cause a congenital myopathy characterized by generalized muscle weakness. Here, we used a multidisciplinary approach to investigate the mechanism of muscle dysfunction in 12 TPM3-myopathy patients. PMID: 26307083
  4. This work expands the phenotypic spectrum of TPM3-related disease and provides insights into the pathophysiological mechanisms of the actin-tropomyosin complex PMID: 26418456
  5. Western blot showed phosphorylation of ALK, ERK1/2, and STAT3 in cells transfected with TPM3-ALK. Coiled-coil structure of TPM3 contributes to the transforming ability of the TPM3-ALK fusion protein, and longer TPM3 region leads to higher dimer formation. PMID: 25596129
  6. DATA show that tropomyosin 3 protein (TPM3) plays a critical role in the progression of gliomas. PMID: 24913705
  7. study reports on a three-generation family with cap myopathy caused by a novel heterozygous mutation in TPM3 PMID: 24239060
  8. TPM3-R167H mutations decreased cooperative thin filament activation in combination with reductions in the myosin cross-bridge number and force production. PMID: 22798622
  9. TPM3 is an interacting partner of granulin-epithelin precursor and may play an important role in hepatocarcinogenesis. PMID: 22792281
  10. investigation of biomarkers for early diagnosis of endometriosis: Data suggest that TPM3, stomatin-like protein 2, and tropomodulin 3 are autoantigens present in blood of women with endometriosis; immunodominant epitopes were identified. PMID: 22158085
  11. study reports clinico-pathological and electrophysiological features of 2 unrelated cases with heterozygous TPM3 mutation; cases highlight neuromuscular transmission defect in congenital myopathy with fibre type disproportion secondary to TPM3 mutations PMID: 20951040
  12. High TPM3-PDGFRB fusion protein expression is associated with chronic eosinophilic leukemia. PMID: 21072821
  13. variation in the tropomyosin isoform composition of microfilaments provides a mechanism to generate functionally distinct filament populations PMID: 21036167

  15. the clinical, myopathological and muscle MRI findings in a German family with autosomal dominant nemaline myopathy due to a novel pathogenic TPM3 mutation PMID: 20012312
  16. Overexpression of TPM3 activates Snail mediated EMT, which will repress E-cadherin expression and that it confers migration or invasion potentials to HCC cells during hepatocarcinogenesis. PMID: 20356415
  17. Conditional TPM3-ALK and NPM-ALK transgenic mice develop reversible ALK-positive early B-cell lymphoma/leukemia. PMID: 20223922
  18. Mutations in TPM3 were identified in 6 out of 13 patients with Congenital fiber type disproportion, as well as in one case of nemaline myopathy. PMID: 19953533
  19. cloned and sequenced a novel nonmuscle tropomyosin (hTM) isoform, TC22, which is strongly associated with colonic neoplasia and carcinoma PMID: 12105844
  20. A mutation converting the stop codon to a serine and a second splicing mutation predicted to prevent inclusion of skeletal muscle exon IX were found associated with nemaline myopathy PMID: 12196661
  21. De novo missense mutation in a constitutively expressed exon of the slow alpha-tropomyosin gene TPM3 associated with an atypical, sporadic case of nemaline myopathy. PMID: 12467750
  22. tropomyosin isoforms regulate neuronal size and shape PMID: 15888546
  23. second pedigree with autosomal dominant nemaline myopathy caused by TPM3 mutation(Arg167His). PMID: 17376686
  24. Mutation of TPM3 is the most common cause of congenital fiber type disproportion reported to date. PMID: 18300303
  25. The mutation reported here is the first deletion to be identified in TPM3, and it is likely to be a founder mutation in the Turkish population. PMID: 18382475
  26. TTC9A acts as a chaperone protein to facilitate the function of tropomyosins (including Tm5NM-1) in stabilizing microfilament and it may play a role in cancer cell invasion and metastasis PMID: 18699990
  27. We report a TPM3 mutation in one of the original cases of cap disease. PMID: 19487656
