Western blot - Anti-ARTS1/ERAP1 antibody [EPR6069] (AB124669)

This blot was produced using 4-20% SDS-PAGE containing 15 μg of K-562 whole cell lysate per lane at 150V for 1hr before being transferred onto a 0.45 μm PVDF membrane at 75V for 1hr. The membrane was then blocked for 1hr using 5% NFDM/TBST, then incubated with ab124669 (1/5000) at room temperature for 1hr. After being washed three times in TBST, the membrane was incubated with Peroxidase conjugated goat anti-rabbit IgG (H+L) (ab97051) at 1/20,000 dilution for 1hr at room temperature. The membrane was washed three times again. Then the signal was developed using the ECL technique. ab124669 was stored at a range of temperatures (+4°C, +22°C, +37°C) for 1 week before being tested in WB. The image shows the band intensity remains relatively constant across all storage temperatures, demonstrating that antibody activity is not affected.

Supplementary information

ARTS1 also known as ERAP1 (Endoplasmic Reticulum Aminopeptidase 1) is an aminopeptidase enzyme with a molecular mass of about 110 kDa. This protein is located in the endoplasmic reticulum and plays a significant mechanical role in trimming peptides for presentation by MHC class I molecules. Its expression is highly detectable in cells with robust antigen-presenting capabilities such as dendritic cells and macrophages. Additionally ARTS1/ERAP1 exists in other tissues where immune surveillance is essential.
Biological function summary

The function of ARTS1/ERAP1 involves the processing of proteolytic fragments preparing them for optimal binding to MHC class I molecules. This enzyme participates in a complex alongside ERAP2 another aminopeptidase working cooperatively to adjust peptide lengths to the correct size necessary for MHC class I presentation. Through this role ARTS1/ERAP1 influences the immune system's ability to detect and respond to infected or neoplastic cells by ensuring that antigenic peptides are properly presented.

Pathways

ARTS1/ERAP1 is a critical component of the antigen processing and presentation pathway. This pathway is essential for the presentation of endogenous antigens to cytotoxic T lymphocytes therefore playing a role in adaptive immunity. Related proteins include MHC class I molecules which present the processed peptides and TAP (Transporter associated with Antigen Processing) which transports peptides into the endoplasmic reticulum for further trimming by ARTS1/ERAP1.

Research links ARTS1/ERAP1 to ankylosing spondylitis and other autoimmune diseases. Variations in the ERAP1 gene may affect peptide trimming efficiency altering the peptide repertoire presented by MHC class I molecules and influencing autoimmune activation. The link to another protein HLA-B27 is notable in ankylosing spondylitis as this MHC class I allele frequently associates with the disease highlighting a complex interaction between ARTS1/ERAP1 enzymatic function and autoimmune susceptibility.

Target data

Aminopeptidase that plays a central role in peptide trimming, a step required for the generation of most HLA class I-binding peptides. Peptide trimming is essential to customize longer precursor peptides to fit them to the correct length required for presentation on MHC class I molecules. Strongly prefers substrates 9-16 residues long. Rapidly degrades 13-mer to a 9-mer and then stops. Preferentially hydrolyzes the residue Leu and peptides with a hydrophobic C-terminus, while it has weak activity toward peptides with charged C-terminus. May play a role in the inactivation of peptide hormones. May be involved in the regulation of blood pressure through the inactivation of angiotensin II and/or the generation of bradykinin in the kidney.
