Fusion peptidesreviews Fusion peptides (FP) are a critical class of molecules primarily recognized for their role in facilitating the fusion of biological membranes作者：LK Tamm·2002·被引用次数：119—Membranefusion peptidesare highly conserved hydrophobic domains of fusion proteins that insert into membranes during membrane fusion.. These peptides, often described as prominent hydrophobic segments, are integral components of viral fusion proteins, playing a pivotal role in processes like viral entry into host cells. Understanding these essential peptides is crucial for advancements in various scientific fields, from virology to drug delivery and therapeutic intervention.Welcome to the sign in page forFusion Peptides. Making an account it easy to access research compounds and supporting products.

The fundamental characteristic of fusion peptides is their amphipathic nature, meaning they possess both hydrophilic and hydrophobic regions. This duality allows them to interact effectively with cell membranes. Research suggests that fusion peptides are typically sequences of 20 to 30 mostly, but not exclusively, apolar residues, although some studies indicate predominantly hydrophobic sequences composed of 16–26 amino acidsSARS-CoV fusion peptides induce membrane surface .... These sequences are often enriched with specific amino acids such as alanine, glycine, and phenylalanine, contributing to their membrane-perturbing capabilities. For instance, SARS-CoV fusion peptides have been shown to strongly perturb the structural integrity of anionic vesicles, supporting the hypothesis that these peptides generate opposing curvature stresses, thereby aiding membrane fusion.

In the context of virology, fusion peptides are believed to initiate viral and cell membrane interactions. When a virus encounters a host cell, the fusion peptide, often present at the N-terminal region of class I viral fusion proteins, extends and inserts into the target cell membrane. This insertion triggers conformational changes in the viral fusion machinery, ultimately leading to the merging of the viral envelope with the host cell membrane, allowing the viral genetic material to enter the cell. Studies on the influenza virus fusion peptide have explored two routes through which the peptides can lower the free energy barrier towards fusion, highlighting the complex mechanisms at play. The planarity of the influenza viral fusion peptide and its ability to change membrane curvature and hydration status are also key areas of investigation.

Beyond their natural roles in viral entry, synthetic fusion peptides have emerged as powerful tools in biotechnology and medicine.The importance of the complete internal fusion peptide ... For example, the TAT-HA2 fusion peptide is recognized for its ability to function as a large macromolecule drug delivery peptideMachine and deep learning to predict viral fusion peptides. The TAT (trans-activator of transcription) protein transduction domain (PTD) within this peptide aids in binding to the cell surface and facilitating cellular entry. This capacity for cell penetration has led to the development of fusion peptide systems with the potential to deliver proteins with a wide range of molecular weights into cells, as demonstrated in experiments involving intact plant cells where such systems delivered proteins ranging from 27 to 150 kDa. Furthermore, novel fusion peptides are being explored to enhance the delivery of exosomes, with in vitro experiments demonstrating that fusion peptides contribute to promoting the positive effect of exosomes on processes like osteogenic differentiation.
