Background: Aminopeptidase PILS/ARTS1

The name of Aminopetidase PILS (Puromycin-Insensitive Leucyl-Specific) describes the two basic properties of this zinc metalloprotease in vitro (1). Also known as ALAP (Adipocyte-derived Leucin AminoPeptidase), type 1 tumor necrosis factor receptor (TNFR) shedding aminopeptidase regulator and ER aminopeptidase ERAP1 or ERAAP, it is encoded by the ARTS1 gene (2-4). Aminopeptidase PILS has been identified to regulate antigen presentation, promote TNFR1 ectodomain shedding and associate with hypertension (2-5).

Protocols

View specific protocols for Recombinant Human Aminopeptidase PILS/ARTS1 Protein, CF (2334-ZN):

Materials
  • Assay Buffer: 25 mM Tris, pH 8.0
  • Recombinant Human Aminopeptidase PILS/ARTS1 (rhARTS1) (Catalog # 2334-ZN)
  • Substrate: Leu-AMC (Bachem, Catalog # I-1240)
  • F16 Black Maxisorp Plate (Nunc, Catalog # 475515)
  • Fluorescent Plate Reader (Model: SpectraMax Gemini EM by Molecular Devices) or equivalent
  1. Dilute rhARTS1 to 2 µg/mL in Assay Buffer.
  2. Dilute Substrate to 600 µM in Assay Buffer.
  3. Load 50 µL of 2 µg/mL rhARTS1 into the plate, and start the reaction by adding 50 µL of 600 µM Substrate. Include a Substrate Blank containing Assay Buffer and Substrate.
  4. Read at excitation and emission wavelengths of 380 nm and 460 nm (respectively), in kinetic mode for 5 minutes.
  5. Calculate specific activity:

     Specific Activity (pmol/min/µg) =

Adjusted Vmax* (RFU/min) x Conversion Factor** (pmol/RFU)
amount of enzyme (µg)

     *Adjusted for Substrate Blank
     **Derived using calibration standard 7-amino, 4-Methyl Coumarin (Sigma, Catalog # A-9891).

Per Well:
  • rhARTS1: 0.1 µg
  • Substrate: 300 µM
