靶點詳情

  • 功能：
    Implicated in immunoproteasome assembly and required for efficient antigen processing. The PA28 activator complex enhances the generation of class I binding peptides by altering the cleavage pattern of the proteasome.
  • 基因功能參考文獻：
    1. Such a modulation of proteasome activity is explained, at least in part, by the circadian expression of both Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and the proteasome activator PA28ab PMID: 26944190
    2. Results show that PA28alpha was found to be overexpressed in oral squamous cell carcinoma cell lines and tumor tissues. High expression of PA28alpha was significantly associated with recurrence and poorer overall survival. PMID: 26892607
    3. Constitutive expression of PA28 and ERAP1 in melanoma cells indicate that both interfere with MART-1(26-35) epitope generation even in the absence of IFN-gamma PMID: 26399368
    4. PA28 is a tumor marker and a potential target for therapeutic intervention in prostate cancer. PMID: 23918357
    5. Reduction in ATP levels triggers immunoproteasome activation by the 11S (PA28) regulator during early antiviral response mediated by IFNbeta in mouse pancreatic beta-cells. PMID: 23383295
    6. the first evidence of a novel ovarian cancer-specific marker PMID: 22532226
    7. PA28 selectively up-regulates the presentation of viral MHC class I epitopes and that down regulation PA28 in tumor cells results in impaired presentation of a human TRP2 tumor antigen. PMID: 12200048
    8. The relationship between anti-PA28alpha and Ki antibodies suggests the importance of an antigen-driven system in the induction of an autoimmune response to PA28 complex. PMID: 14760793
    9. DJ-1 and PA28alpha may have roles in the onset of hepatocarcinogenesis PMID: 17671684
    10. the 11S proteasome activator complex, Reg alpha fragment, may have a role in ovarian cancer PMID: 17939699
    11. bortezomib-adapted HL-60 cells showed increased expression and proteasome association of the 11S proteasome activator PMID: 19225532
