一般說明
Chemical structure: peptide
Defensins (α and β) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The α-defensins which include neutrophil peptides-1, -2 and -3, (NP-1, NP-2 and NP-3) are distinguished from the β-defensins by the pairing of their three disulfide bonds. Neutrophil-1 (NP-1) is expressed as the C-terminal portion of an inactive precursor protein, which also contains a 19 amino acid N-terminal signal sequence and a 45 amino acid polypeptide. The protein contains a six-cysteine motif that forms three intra-molecular disulfide bonds. It is a transmembrane glycoprotein. Recombinant human NP-1 is a 3.4kDa protein containing 30 amino acid residues.
生化／生理作用
Neutrophil peptide-1 (NP-1) exhibits antimicrobial activity. It also has a chemotactic function in dendritic cells. It has a role in the growth and metastasis of cancer cells. The protein acts as multifunctional co-receptor and interacts with various signaling cascades. NP-1 associates with epithelial growth factor (EGF) and its receptor (EGFR). It also interacts with hepatocyte growth factor (HGF) and its receptor c-Met.

重構
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

The interaction between VEGF-A and its neuropilin (NRP) receptors mediates a number of important biological effects. NRP1 and the related molecule NRP2 are widely expressed on multiple tumour types and throughout the tumour vasculature, and are emerging as critical molecules

The purpose of this study was to determine the correlation between over-expression of the neuropilin 1 (NRP1) gene and growth, survival, and radio-sensitivity of non-small cell lung carcinoma (NSCLC) cells. 3-[4,5-dimethylthylthiazol-2-yl]-2,5 diphenyltetrazolium broide (MTT) and colony assays were then performed

Analysis of rhesus macaque leukocytes disclosed the presence of an 18-residue macrocyclic, tridisulfide antibiotic peptide in granules of neutrophils and monocytes. The peptide, termed rhesus theta defensin-1 (RTD-1), is microbicidal for bacteria and fungi at low micromolar concentrations. Antibacterial activity
