ターゲット情報

  • 機能Activates EIF2AK2/PKR in the absence of double stranded RNA (dsRNA), leading to phosphorylation of EIF2S1/EFI2-alpha and inhibition of translation and induction of apoptosis. Required for siRNA production by DICER1 and for subsequent siRNA-mediated post-transcriptional gene silencing. Does not seem to be required for processing of pre-miRNA to miRNA by DICER1.
  • 関連疾患Defects in PRKRA are the cause of dystonia type 16 (DYT16) [MIM:612067]. DYT16 is an early-onset dystonia-parkinsonism disorder. Dystonia is defined by the presence of sustained involuntary muscle contraction, often leading to abnormal postures. DYT16 patients have progressive, generalized dystonia with axial muscle involvement, oro-mandibular (sardonic smile) and laryngeal dystonia and, in some cases, parkinsonian features.
  • 配列類似性Belongs to the PRKRA family.
    Contains 3 DRBM (double-stranded RNA-binding) domains.
  • ドメインSelf-association may occur via interactions between DRBM domains as follows: DRBM 1/DRBM 1, DRBM 1/DRBM 2, DRBM 2/DRBM 2 or DRBM 3/DRBM3.
  • 翻訳後修飾Phosphorylated at Ser-246 in unstressed cells and at Ser-287 in stressed cells. Phosphorylation at Ser-246 appears to be a prerequisite for subsequent phosphorylation at Ser-287. Phosphorylation at Ser-246 and Ser-287 are necessary for activation of EIF2AK2/PKR under conditions of stress.

  • Predicted band size : 34 kDa

    Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: PACT (PKR activating protein)/PRKRA knockout HAP1 cell lysate (20 µg)
    Lane 3: K562 cell lysate (20 µg)
    Lane 4: HepG2 cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab31967 observed at 36 kDa. Red - loading control, ab18058, observed at 124 kDa.
    ab31967 was shown to recognize PACT (PKR activating protein)/PRKRA when PACT (PKR activating protein)/PRKRA knockout samples were used, along with additional cross-reactive bands. Wild-type and PACT (PKR activating protein)/PRKRA knockout samples were subjected to SDS-PAGE. ab31967 and ab18058 (loading control to Vinculin) were diluted at 1 μg/ml and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

  • ICC/IF image of ab31967 stained human HeLa cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab31967, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

  • PACT (PKR activating protein) / PRKRA was immunoprecipitated using 0.5mg Mouse Testis tissue, 5µg of Rabbit polyclonal to PACT (PKR activating protein) / PRKRA and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Mouse Testis tissue lysate lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab31967.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
