Form	Liquid or Lyophilized powder
Buffer	Liquid form: default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Lyophilized powder form: the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution	Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%.
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	Major component of the type IV pilus (T4P) that plays a role in surface and host cell adhesion, colonization, biofilm maturation, virulence, and twitching, a form of surface-associated motility facilitated by cycles of extension, adhesion, and retraction of T4P fibers. In addition, plays a critical role in type II secretion of exoenzymes by interacting with specific components such as XcpT or XcpU. Modulates host calcium signaling through interaction with host calcium-modulating cyclophilin ligand.
Subcellular Location	Fimbrium. Cell inner membrane; Single-pass membrane protein. Host endoplasmic reticulum membrane.
Protein Families	N-Me-Phe pilin family
Database References	KEGG: pae:PA4525 STRING: 208964.PA4525

Gene Functions References

Glycosylation of type 4 fimbrial protein (PilA) protect Pseudomonas aeruginosa from certain pilus-specific phages. Alterations to PilA sequence can block phage infection, but glycosylation is less likely to create disadvantageous phenotypes. Through construction of chimeric phages, specific phage tail proteins allow infection of P. aeruginosa strains with glycosylated pili. PMID: 29133883
PilS's phosphatase motif was required for the autoregulation of pilA transcription, suggesting that under conditions where PilA is abundant, the PilA-PilS interaction promotes PilR dephosphorylation and thus down-regulation of further pilA transcription. PMID: 27162347
Data show that the type IV pilus (Tfp)-deficient mutant DeltapilA is severely attenuated in an acute pneumonia model of infection in the lungs of wild-type mice, but is virulent in the lungs of surfactant protein-A SP-A(-/-) mice. PMID: 24080545
Found that the calcium-modulating cyclophilin ligand (CAMLG), which is involved in Ca(2+) signaling, was the major host cell PilA binding protein. PMID: 23266901
PilA, the major pilin subunit, interacts with PilNOPQ. The results allow us to propose a model whereby PilA makes extensive contacts with the transenvelope complex, possibly to increase local concentrations of PilA monomers for polymerization. PMID: 23457250

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.
