Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Alexa Fluor® 488 Anti-PR3 antibody [EPR23253-35] (AB282665)

Immunofluorescence staining of PR3 staining in a section of formalin-fixed paraffin-embedded human normal spleen*.

Performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with EDTA (pH9.0) using retrieval settings of 110°C for 20 minutes. The section was then incubated at room temperature for 1 hour with ab282665 at 1/100 dilution (shown in green) and counterstained using ab190573, Rabbit anti-Tubulin (A647)(1/250) at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Dako Fluorescence Mounting Medium®.

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

For other IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antigen retrieval conditions, antibody concentrations and incubation times.

Supplementary information

Proteinase 3 (PR3) also known as PRTN3 is a serine protease with a mass of approximately 29 kDa. It belongs to the human neutrophil elastase (HNE) family and is mainly expressed in neutrophils. Within these immune cells PR3 localizes to azurophilic granules where it participates in early immune responses. The proteolytic activity of PR3 involves cleaving peptide bonds in target proteins contributing to the processing and degradation of various proteins important for immune function.
Biological function summary

Proteinase 3 serves multiple roles including modulating inflammation and immune responses. PR3 functions as part of a complex with azurophilic granules aiding in microbial defense mechanisms. In addition the protease regulates cytokine activation and deactivation which in turn influences cell signaling related to inflammation. Its enzymatic action ensures that PR3 can manage inflammatory processes by breaking down extracellular matrix components thereby allowing white blood cells to access infection sites.

Pathways

Proteinase 3 plays an important role within the serine protease and inflammatory pathways. It interacts with other proteins such as neutrophil elastase with which it shares a pathway to modulate immune responses. PR3 also partners with cathepsin G contributing to processes such as pathogen clearance and tissue remodeling providing a coordinated response during infection and injury. These interactions show PR3's involvement in regulating the balance between inflammation and tissue repair.

PR3 is notably associated with Wegener's granulomatosis also known as granulomatosis with polyangiitis. This autoimmune condition results in systemic vasculitis where anti-proteinase 3 antibodies notably characterize the disease. Additionally PR3 plays a part in chronic obstructive pulmonary disease (COPD) where its proteolytic activity contributes to tissue damage in the lungs. In both conditions PR3 interplays with related proteins like myeloperoxidase further demonstrating its importance in processes leading to these disorders.

Target data

Serine protease that degrades elastin, fibronectin, laminin, vitronectin, and collagen types I, III, and IV (in vitro) (PubMed : 2033050, PubMed : 28240246, PubMed : 3198760). By cleaving and activating receptor F2RL1/PAR-2, enhances endothelial cell barrier function and thus vascular integrity during neutrophil transendothelial migration (PubMed : 23202369). May play a role in neutrophil transendothelial migration, probably when associated with CD177 (PubMed : 22266279).
