TAT-Beclin Scrambled is a scrambled version of the peptide derived from a region of the Beclin 1 protein. The original peptide interacts with a newly identified negative regulator of autophagy, GAPR-1 (also called GLIPR2) to act as a potent inducer of autophagy. Autophagy is an essential process that maintains cellular homeostasis and carries out lysosome-mediated degradation of unwanted proteins in the cytoplasm. It is often examined when looking at disease pathways because of this regulatory function. While the immune system initiates the removal of viruses and pathogens through the autophagic pathway, some viruses (such as HIV) are able to evade this process.The scrambled sequence in this peptide means it can be used as an effective negative control in such experiments because whilst it contains the same amino acids as Beclin-1 (and thus has the same molecular weight), it does not express the same properties as the original peptide.TAT (47-57) is present due to its properties as a cell penetrating cationic peptide (CPP). It derived from the N-terminus of the Tat protein, which is a trans-activator of the transcription protein present in the human immunodeficiency virus (HIV). As a CPP, TAT (47-57) is able facilitate the delivery of the Beclin Scrambled protein across the plasma membrane.This peptide contains a GG linker between the C-terminus of TAT (47-57) and the N-terminus of Beclin Scrambled.

The cyclic pentapeptide cyclo(Arg-Gly-Asp-[D-Phe]-Lys) is a highly potent and selective inhibitor for the alphavβ3 integrin receptor. A related compound, cyclo(Arg-Gly-Asp-[D-Phe]-Val), is a promising anticancer drug candidate- it inhibits angiogenesis and induces apoptosis in vascular cells.Cyclic RGD-containing peptides are selective antagonists of integrins, proteins that play important roles in cell-cell and cell-matrix interactions. In a suitably labelled form, these peptides may serve as useful tools for diagnostic imaging and peptide targeted therapy of some types of cancer.

Pro B-type natriuretic peptide (Pro-BNP) is secreted from cardiac myocytes and cleaved into BNP and the remaining part of the prohormone N-terminal proBNP (NT-proBNP). When the heart fibres become stretched more BNP and NT-proBNP are released to try and compensate for the increased pressure. During heart failure the walls of the atria become over stretched and thus increase the levels of NT-proBNP detectable. NT-proBNP has a longer half-life than BNP and therefore is detectable at higher levels in blood plasma than BNP. NT-pro-BNP is believed to be cleared by renal excretion, but this is not confirmed. As a diagnostic tool, NT-proBNP (47-76) has become very useful in helping diagnose heart failure and provide a prognosis. The measurement of NT-proBNP (47-76) has been incorporated into management and guidelines of clinical settings. As a research tool it still provides valuable data such as symptoms onset in relation to NT-proBNP levels and how inflammation effects the level of BNP as well as the BNP/ NT-proBNP ratio.

Amino acids 1-17 of human adrenocorticotropic hormone (ACTH). ACTH, also known as corticotropin, is a tropic hormone produced and secreted by the anterior pituitary gland and member of the melanocortins peptide family. ACTH is cleaved from the precursor proopiomelanocortin (POMC). ACTH is an important component of the hypothalamic-pituitary-adrenal (HPA) axis and is often produced in response to biological stress. ACTH acts to increase the production and release of cortisol via its interaction with the ACTH receptor- ACTHR, also known as melanocortin type 2 receptor (MC2R). Receptor activation increases the intracellular concentration of cAMP via adenylyl cyclase.Abnormal ACTH levels in the body has been linked to primary adrenal insufficiency/Addison's disease, Cushing's disease and secondary adrenal insufficiency.

Post-transmembrane region (PTM) from the envelope protein (E) of the coronavirus- Mouse Hepatitis Virus (MHV). This protein region is involved in direct membrane binding, with the C-terminal hydrophobic residues of this peptide, thought to be most relevant for membrane binding. After replication, coronaviruses (CoVs) assemble on intracellular membranes, the coronavirus envelope protein (E) is involved in virus assembly and release. E proteins have been located in the endoplasmic reticulum Golgi intermediate compartment (ERGIC) and Golgi of infected cells but are not thought to traffic to the cell surface of infected cells. CoV E is a small hydrophobic protein which is conserved between coronaviruses. E consist of a short hydrophilic amino terminal region, a hydrophobic transmembrane region and a carboxy-terminal region. CoV E protein is an integral membrane protein.E has been considered a therapeutic target for SARS-CoV-2.

Histone 4 (H4) is one of the four core histones (H2A, H2B, H3 and H4) which are fundamental in compacting eukaryotic DNA into the nucleosome. Due to the high lysine and arginine content, histones have a net positive charge and therefore electrostatically interact with negatively charged DNA. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Like other core histones, H4 has a globular domain and a flexible N-terminal domain, the histone tail, which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination.Gene transcriptional activation or inactivation is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes. Both processes function to alter the positioning of the nucleosome, allowing the DNA within to be either accessible to the transcription machinery or inaccessible. H4's lysine rich tail plays a role in the higher order chromatin folding.Modifications allow histones to contribute to gene regulation, chromosome condensation and DNA repair. In yeast, methylation of R3 of Histone 4 results in the recruitment of histone acetyl transferase to the chromatin and the acetylation of Histone 4 K5.
