  • IHC image of CSB-RA943230A0HU diluted at 1:100 and staining in paraffin-embedded human small intestine tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

Description

Generating the PSME1 recombinant monoclonal antibody involves a series of intricate processes. It starts with harvesting the PSME1 monoclonal antibody and sequencing its gene. A vector carrying the PSME1 monoclonal antibody gene is then constructed and introduced into a host cell line for culture. During PSME1 monoclonal antibody production, a synthesized peptide based on human PSME1 is utilized as the immunogen. The PSME1 recombinant monoclonal antibody is subsequently purified using affinity chromatography from the cell culture supernatant and subjected to ELISA, WB, IHC, IF, and FC applications to verify its specificity. It only detects human PSME1 protein.

PSME1, also known as PA28α, is a regulatory subunit of the 20S proteasome complex. It forms a complex with the subunit PSME2 (PA28β) and binds to the ends of the 20S proteasome, activating its proteolytic activity. PSME1 enhances the proteasomal degradation of antigenic proteins presented on MHC class I molecules, promoting their recognition by T lymphocytes. In addition, PSME1 plays a role in cell cycle progression and apoptosis and is involved in the regulation of various cellular processes such as DNA repair and transcriptional regulation.

Target Background

Function
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.
Gene References into Functions
  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
