Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Details

Target Function	Broad specificity aminopeptidase which plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. Also involved in the processing of various peptides including peptide hormones, such as angiotensin III and IV, neuropeptides, and chemokines. May also be involved the cleavage of peptides bound to major histocompatibility complex class II molecules of antigen presenting cells. May have a role in angiogenesis and promote cholesterol crystallization. It is able to degrade Leu-enkephalin and Met-enkephalin but not cholecystokinin CCK8, neuromedin C (GRP-10), somatostatin-14, substance P and vasoactive intestinal peptide. May have a role in amino acid transport by acting as binding partner of amino acid transporter SLC6A19 and regulating its activity.; (Microbial infection) In case of porcine transmissible gastroenteritis coronavirus (TGEV) and porcine respiratory coronavirus (PRCoV) infections, serves as a receptor for TGEV and PRCoV spike glycoprotein in a species-specific manner.
Subcellular Location	Cell membrane; Single-pass type II membrane protein.
Protein Families	Peptidase M1 family
Database References	KEGG: ssc:397520 STRING: 9823.ENSSSCP00000029051 UniGene: PMID: 28363778 pAPN is not a functional receptor for porcine epidemic diarrhea virus, but promotes the infection of PEDV through its protease activity. PMID: 27449937 The C-terminal domain of the S1 domain of porcine epidemic diarrhea virus is bound to swine pAPN. PMID: 26907329 Data indicate that fluorogenic substrates can be successfully used to identify aminopeptidase N and to measure their activity in cell lysates. PMID: 26449746 SPC subdomain of APN plays a key role in cell entry of PEDV and its expression permits PEDV growth PMID: 26044794 Porcine epidemic diarrhea virus recognizes protein receptor aminopeptidase N from pig and human and sugar coreceptor N-acetylneuraminic acid. PMID: 25787280 These data demonstrate that pAPN, the cellular receptor for porcine epidemic diarrhea virus, mediates polarized virus infection. PMID: 25681796 It was concluded that the difference in F4 binding to ANPEP is due to modifications in its carbohydrate moieties. PMID: 24663207 The region aa 673-722 of the C subunit of porcine aminopeptidase N is indicated to play a key role in swine transmissible gastroenteritis virus binding. PMID: 22083718 The binding ability of four truncated porcine aminopeptidase N proteins to transmissible gastroenteritis virus (TGEV), a porcine coronavirus, was analyzed by ELISA and immunoblotting. PMID: 20643168 Aminoeptidase N is the major for cell entry system of porcine epidemic diarrhea virus infection. PMID: 20074871 results demonstrate that aminopeptidase N reduces basolateral Na(+)-K(+)-ATPase levels via ANG IV/AGTRIV signaling. This novel pathway may be important in renal adaptation to high salt PMID: 17634404

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
