靶點詳情

  • 功能：
    Plays an important role in caveolae formation and organization. Essential for the formation of caveolae in all tissues. Core component of the CAVIN complex which is essential for recruitment of the complex to the caveolae in presence of calveolin-1 (CAV1). Essential for normal oligomerization of CAV1. Promotes ribosomal transcriptional activity in response to metabolic challenges in the adipocytes and plays an important role in the formation of the ribosomal transcriptional loop. Dissociates transcription complexes paused by DNA-bound TTF1, thereby releasing both RNA polymerase I and pre-RNA from the template. The caveolae biogenesis pathway is required for the secretion of proteins such as GASK1A.

    1. PTRF inhibits the proliferation, migration, and invasion of colorectal cancer cells. Future studies need to define the role of PTRF in the regulation of chemo-resistance in colorectal cancer cells and in colorectal cancer stem cells. PMID: 27203393
    2. Purified Cavin1 60S complexes were analyzed structurally in solution and after liposome reconstitution by electron cryotomography. Cavin1 adopted a flexible, net-like protein mesh able to form polyhedral lattices on phosphatidylserine-containing vesicles. Mutating the two coiled-coil domains in Cavin1 revealed that they mediate distinct assembly steps during 60S complex formation. PMID: 27834731
    3. Data suggest that the predominant plasmalemmal anionic lipid phosphatidylserine is essential for proper caveolin/cavin clustering, caveola formation, and caveola dynamics; membrane scrambling (by using other phospholipids) can perturb caveolar stability; these studies involved caveolin-1 and cavin-1 as models of caveolin/cavin clustering. PMID: 28698382
    4. DNA methylation profiling identifies PTRF/Cavin-1 as a novel tumor suppressor in Ewing sarcoma when co-expressed with caveolin-1, which PTRF, disrupts the MDM2/p53 complex, leading to apoptosis. PMID: 27894957
    5. Results show that PTRF is a direct target of miR-187. PTRF plays crucial roles in miR-187-induced epithelial-mesenchymal transition and migration of non-small cell lung cancer cells. PMID: 28393200
    6. The expression of the PTRF protein was significantly weaker than that in the adjacent normal lung tissues using immunohistochemical staining.

    7. A homozygous PTRF mutation was identified in patient-1. Congenital generalized lipodystrophy type 4 was caused by homozygous PTRF c.481-482insGTGA (p.Lys161Serfs*41) mutation in patient-2. PMID: 27167729

    9. Cavin-1 and cavin-2 are strongly expressed within caveolae-like structures within liver sinusoidal endothelial cells of the hepatitis C-related cirrhotic liver and cavin-1 would play a critical role in regulating aspects of caveolin-1. PMID: 26086560
    10. Rather than forming a single coat complex containing the three cavin family members, single-molecule analysis reveals an exquisite specificity of interactions between cavin1, cavin2 and cavin3. PMID: 24473072
    11. Our data support a role for PTRF/cavin-1, through caveolae formation, as an attenuator of the non-caveolar functionality of Cav1 in Gal3-Cav1 signalling and regulation of focal adhesion dynamics and cancer cell migration. PMID: 25942420
    12. this study presents a novel mutation of PTRF from Saudi Arabia and our findings broaden the mutation spectrum of PTRF in the familial CGL4 phenotype. PMID: 25721873
    13. cavin3 is recruited to the caveolae coat by cavin1 to interact with caveolin1 and regulate the duration time of caveolae at the plasma membrane. PMID: 25588833
    14. The presence of caveolae as an anatomic structure is not sufficient to ensure their proper function in patient with PTRF mutation. PMID: 25904680
    15. Using in silico and in vitro analysis we show that Cavin-1 is expressed in myogenic Rhabdomyosarcoma tumors and human and primary mouse RMS cultures. Cavin-1 or Cav-1 knockdown led to impairment of cell proliferation and migration. PMID: 25822667

    27. PTRF/cavin-1 is a novel regulator of oxidative stress-induced premature senescence by acting as a link between free radicals and activation of the p53/p21(Waf1/Cip1) pathway. PMID: 21705337
    28. PTRF/cavin-1-expressing PC3 cells exhibit decreased migration, and that this effect is mediated by reduced MMP9 production. PMID: 20732728
    29. membrane-delimited interaction between MG53 and PTRF contributes to initiation of cell membrane repair PMID: 21343302
