Human LRAP/ERAP2 Protein Product Information
Synonym:FLJ23633, FLJ23701, FLJ23807, L-RAP, LRAP.ERAP2
Protein Construction:A DNA sequence encoding the lumenal domain of human ERAP2 (NP_071745.1) (Ala 56-Thr 960) was expressed with a polyhistidine tag at the N-terminus.
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human LRAP/ERAP2 Protein QC Testing
Purity:> 98 % as determined by SDS-PAGE
Bio-Activity:Measured by its ability to cleave the fluorogenic peptide substrate, Arg-7-amido-4-methylcoumarin (Arg-AMC). The specific activity is >50 pmoles/min/μg.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Leu 24
Molecule Mass:The recombinant human ERAP2 consists of 921 amino acids and predictes a molecular mass of 106 kDa. In SDS-PAGE under reducing conditions, it migrates with the apparent molecular mass of 115-125 kDa due to glycosylation.
Formulation:Lyophilized from sterile 12.5mM Tris, 75mM NaCl, pH 7.5, 50% glycercol
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Human LRAP/ERAP2 Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

ERAP2  Background

Leukocyte-derived arginine aminopeptidase (LRAP), also known as endoplasmic reticulum-aminopeptidase 2 (ERAP2), is the second identified aminopeptidase localized in the in the lumenal side of endoplasmic reticulum (ER) processing antigenic peptides presented to major histocompatibility complex (MHC) class I molecules. It is a 960-amino acid protein with significant homology to placental leucine aminopeptidase and adipocyte-derived leucine aminopeptidase. LRAP preferentially hydrolyzes the basic residues Arg and Lys, and contains the HEXXH(X)18E zinc-binding motif, which is the characteristic of the M1 family of zinc metallopeptidases which also includes PILS/ARTS1/ERAP1 and LNPEP/PLAP. Induced by interferon-gamma, LRAP is able to trim various MHC class I antigenic peptide precursors.
