    靶标

    • 功能

      Pro-apoptopic protein capable of selectively inducing apoptosis in cancer cells, sensitizing the cells to diverse apoptotic stimuli and causing regression of tumors in animal models. Induces apoptosis in certain cancer cells by activation of the Fas prodeath pathway and coparallel inhibition of NF-kappa-B transcriptional activity. Inhibits the transcriptional activation and augments the transcriptional repression mediated by WT1. Down-regulates the anti-apoptotic protein BCL2 via its interaction with WT1. Seems also to be a transcriptional repressor by itself. May be directly involved in regulating the amyloid precursor protein (APP) cleavage activity of BACE1.
    • 组织特异性

      Widely expressed. Expression is elevated in various neurodegenerative diseases such as amyotrophic lateral sclerosis, Alzheimer, Parkinson and Huntington diseases and stroke. Down-regulated in several cancers.
    • 结构域

      The leucine-zipper domain is not essential for apoptosis, but is required for sensitization of cells to exogenous apoptotic insults and for interaction with its partners.
      The SAC domain is a death-inducing domain selective for apoptosis induction in cancer cells. This domain is essential for nuclear entry, Fas activation, inhibition of NF-kappa-B activity and induction of apoptosis in cancer cells.
    • 翻译后修饰

      Preferentially phosphorylated at the Thr-163 by PKC in cancer cells.
    • 细胞定位

      Cytoplasm. Nucleus. Mainly cytoplasmic in absence of apoptosis signal and in normal cells. Nuclear in most cancer cell lines. Nuclear entry seems to be essential but not sufficient for apoptosis (By similarity). Nuclear localization includes nucleoplasm and PML nuclear bodies.

      Question

      vielen Dank für die schnelle Antwort. Da wir auf der Suche nach einem PAR-4 Antikörper sind, der PAR-4 C-terminal von der Caspase Schnittstelle erkennt, hätte Abcam ja noch einen zur Auswahl. (PAR-4 rab polycl. ab5787; Immunogen Synthetic peptide: EQLKQENKTLLKVVGQLTR, corresponding to amino acids 324-342 of Human PAR4).
      Den hätten wir als Ersatz für den PAR-4 ab49155 bitte zugeschickt. Falls Sie noch weitere Infos benötigen stehe ich Ihnen gerne zur Verfügung.

      Question

      Would like positive and negative control tissue slides for TRAIL and PAR4. Needs blocking peptide for PAR4 antibody as it is ubiquitously expressed.

      Asked on Oct 20 2011

      Answer

      Thanks for your call earlier this week and for your patience. The immunogenic peptide for the PAR4 antibody ab5787 is available as ab5853- https://www.abcam.com/PAR4-peptide-ab5853.html You can use this peptide in a blocking assay in order to demonstrate the specificity of the antibody, since there is not negative control tissue available. Please let me know if you have any questions or if there is anything else that I can do for you.

      Question

      I have a complaint about the Par4 antibody AB5787 (Lot. 45056) which seems to bind unspecific in WB of HT22 celllysate. Our customer has reviewed your suggestions and done some additional experiments - unfortunately without success. Here are his answers to your questions: 1. This antibody has been characterized on human and rat samples for Western blot application. Other species have not been tested so we do not know if it recognizes mouse PAR4. It is expected to cross-react with mouse (100% identity with immunogen) due to sequence homology but we have no data yet. - "Now tried the antibody with proteins extracted from rat neurons. The result was as bad as before". 2. As I understand the customer has multiple bands. How much protein was loaded onto the gel? We usually recommend 20-30 ug total protein/lane. If the gel is overloaded, multiple bands can be seen. - "I loaded the gel several times with 50µg and several times with 25µg protein. At the lower loaded gel there also were mutliple bands". 3. Has the customer used protease inhibitors in the lysis buffer? No information in the e-mail. - "There was protease inhibitor cockatil in the lysis buffer". 4. It is also important to test the secondary antibody "run a secondary control" to see if the detection system works properly. Has he tested this? Or has he used the same secondary antibody with another primary antibody? What exactly the specification of the secondary antibody? - "The secondary antibody is polyclonal anti rabbit and it works great with other primary antibodies". 5. We would also recommend using positive control along with the samples. Rat tissue extracts, including testes, spleen, ovary, lung, and skeletal muscle would be good positive control. The customer should be able to see a 40 kDa and a 38 kDa protein bands. - "In cells transfected with Par4-Plasmid I cant see any bands at 40 or 38 kDa. Just the many other bands". Do you have any further suggestions?

      Asked on Jun 15 2004

      Answer

      Thank you for your patience. In reviewing the information, we see Western blot with multiple bands at 40 kDa, 38 kDa and unknown at 20 kDa. It is most likely that the preparation, protocol or storage of antibody that is causing the extra bands. There may be homologous sequences in this protein because in reference papers, we noticed all the researchers have cut out the target band and did not reveal the entire blot. This occurs mostly when they want to avoid revealing multiple bands. We would suggest increasing the stringency of their washes and blocking (increase detergent/salt concentration, increase temperatures and times, while decreasing the concentration of primary antibody being used.) We would also recommend using positive controls, to show which bands are relevant. We hope this helps.
