Buforin II is a highly potent antimicrobial peptide which was derived from buforin I, a peptide isolated from the stomach of the Asian toad, Bufo bufo garagrizans. Buforin II is an alpha-helical antimicrobial peptide, however it has far stronger antimicrobial activity against a broad spectrum of microorganisms compared with other alpha-helical antimicrobial peptides. Buforin II may have a different mode of action to that of other alpha-helical peptides targeting nucleic acids instead of cell membranes.

Recombinant human interferon-β (IFNB) is a therapeutic for specific stages of multiple sclerosis (MS). However, a significant portion of patients develop neutralising antibodies within two years which prevent the clinical efficacy of the treatment- this was correlated to a specific rise in IgG. Sequencing of IFNB1 revealed CD4+ T cell epitope residues (118-132) that contain critical T cell activation residues. Identifying these sequences allows them to be manipulated to provide new interferon treatments that reduce the capacity to induce neutralising antibodies in MS patients. In addition, the critical residue isoleucine has been mutated to valine and shown to reduce the immunological response to this epitope. This IFNB1 (118-132) epitope can be used for immunological investigations as a deimmunised version of the epitope. In addition, it can be used as a control for T cell activation and antibody recognition via immunoassays and immunohistochemistry. This may provide further insights into specific haplotypes correlating to IFNB responses in MS treatment.

Thrombin receptor inhibitory peptide (TRIP). Thrombin activates members of the PAR family of receptors to initiate a variety of signalling pathways.Protease activated receptors (PARs) are a distinctive four-member family of seven transmembrane G protein-coupled receptors (GPCRs) widely expressed in inflammatory cells. PARs are cleaved by certain serine proteases to expose a tethered ligand domain, this ligand domain then binds to and activates the receptors to initiate multiple signalling cascades. This peptide mimics the tethered peptide ligand of PAR- 2, but lacks the S42 residue which is important for receptor activation, and therefore acts as a thrombin antagonist peptide.

The PA protein is a subunit of the influenza virus polymerase complex and its endonuclease activity is vital in viral genome replication. As a phosphoprotein it is a casein kinase substrate and its N-terminus is responsible for the activation of a proteolytic process in which co-expressed proteins are degraded.During viral RNA synthesis PA produces 5' capped RNA oligonucleotides due to it cleaving the 5' terminus on pre-mRNA. It is possible that the PA protein could be used as a target in antiviral chemotherapy.

Apolipoprotein A-I enables the efflux of fat molecules from within cells as high-density lipoprotein (HDL) particles for transport back into LDL particles or to the liver for excretion. HDLs are one of five major groups of lipoproteins. Increasing concentrations of HDL particles are strongly associated with decreasing accumulation of atherosclerosis within the walls of arteries. Apolipoprotein A-I is often used as a biomarker for prediction of cardiovascular diseases, such that low levels of APOA1 are associated with an increased risk of adverse events in patients with coronary artery disease. In such cases, APOA1 can be used as a biomarker to predict cardiovascular disease progression.This peptide contains a covalently bonded N-terminal Biotin tag that can be used for detection and purification.

Amylin, also known as islet amyloid polypeptide (IAPP), is a peptide hormone which is deficient in patients with diabetes mellitus (DM). Amylin is co-secreted with insulin from the pancreatic β-cells. It inhibits glucagon secretion, delays gastric emptying, and thus acts as a satiety agent.  Amylin peptide is capable of forming aggregates, and pancreatic amyloid plaques are present in 90% of patients with DM. Formation of these plaques may be inhibited by insulin via the formation of heteromolecular complexes. Amylin is also involved in adiposity signalling and body weight regulation.Amylin is expressed in the human placenta during pregnancy where it may help regulate food intake by both the mother and foetus, and is involved in foetal development of bone, kidneys and pancreas.
