Product Details


CUSABIO synthesized the recombinant gene by integrating the N-terminal 6xHis tag sequence into the targeted gene encoding the 1-732aa of the human APEH. The synthesized gene was subsequently cloned into an expression vector. After cloning, the expression vector was introduced into the E.coli for expression. The product was purified to obtain the recombinant human APEH protein carrying N-terminal 6xHis tag. The SDS-PAGE assayed the purity of this recombinant APEH protein greater than 85%. This APEH protein migrated along the gel to a band of about 90 kDa molecular weight.

APEH is a gene providing instruction of making a protein called acylamino-acid-releasing enzyme in human and belongs to peptidase S9C family. This protein, also abbreviated APH or AARE, is a tetrameric serine protease which specifically removes acetyl amino acids from N-terminally acetylated peptides and play an important role in destroying oxidatively-damaged proteins in living cells. APH preferentially cleaves off Ac-Ala, Ac-Met and Ac-Ser. Deletions of this gene locus are found in various types of carcinomas, including small-cell lung carcinoma and renal cell carcinoma.

Purity Greater than 85% as determined by SDS-PAGE.

Form Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein FAQs
Storage Condition Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time 3-7 business days
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

This enzyme catalyzes the hydrolysis of the N-terminal peptide bond of an N-acetylated peptide to generate an N-acetylated amino acid and a peptide with a free N-terminus. It preferentially cleaves off Ac-Ala, Ac-Met and Ac-Ser.
Gene References into Functions
  1. Although APEH is primarily localized in the cytoplasm, a sub-fraction of this enzyme is sequestered at sites of nuclear damage following UVA irradiation or following oxidative stress. APEH interacts with the amino-terminal domain of XRCC1, and APEH facilitates both single-strand break repair and cell survival following exposure to H2O2. Thus, APEH as a novel proteolytic component of the DNA damage response. PMID: 28866241
  2. APEH polymorphism has significant influence on valproic acid pharmacokinetics in Chinese population PMID: 27406852
  3. Studies indicate that the cylindromatosis/turban tumor syndrome gene (CYLD) ranked highest, followed by acylaminoacyl-peptidase (APEH), dystroglycan (DAG1), macrophage-stimulating protein (MST1) and ubiquitin-specific peptidase 4 (USP4). PMID: 21931648
