Folding in Biology §

Group: 4 #group-4

Relations §

• Quaternary Structure: The quaternary structure of a protein refers to the arrangement of multiple folded polypeptide chains into a larger complex.
• Protein Aggregation: Misfolded proteins can aggregate into insoluble clumps, which can be toxic to cells.
• Tertiary Structure: The tertiary structure of a protein refers to its 3D shape, which is determined by folding.
• Chaperone Proteins: Chaperone proteins assist in the proper folding of other proteins.
• Ribozymes: Ribozymes are RNA molecules that can catalyze chemical reactions, and their function depends on proper folding.
• DNA Folding: DNA molecules can also fold into higher-order structures, which is important for processes like gene regulation and packaging within chromosomes.
• Chromatin Structure: The folding and packaging of DNA into chromatin structures is essential for regulating gene expression and organizing the genome.
• Histone Proteins: Histone proteins play a crucial role in the folding and packaging of DNA into chromatin structures.
• RNA Folding: Like proteins, RNA molecules can fold into specific 3D structures that are essential for their function.
• Nucleosomes: Nucleosomes are the basic units of chromatin, consisting of DNA wrapped around histone proteins.
• Protein Folding: Protein folding is the process by which a protein structure assumes its functional 3D shape from a linear chain of amino acids.
• Epigenetics: Epigenetic modifications can influence the folding and accessibility of chromatin, affecting gene expression.
• Riboswitches: Riboswitches are regulatory segments of RNA that can change their structure and function in response to specific molecules.
• Fold Geometry: Folding processes in biology, such as protein folding and DNA packaging, are studied using fold geometry concepts.
• Gene Expression: The folding and organization of DNA and chromatin structures are essential for regulating gene expression in cells.
• Prions: Prions are infectious misfolded protein particles that can cause other proteins to misfold.
• Neurodegenerative Diseases: Protein misfolding and aggregation are believed to play a role in the development of neurodegenerative diseases like Alzheimer’s and Parkinson’s.
• Amyloid Fibrils: Amyloid fibrils are insoluble fibrous protein aggregates formed by misfolded proteins, implicated in diseases like Alzheimer’s.
• Secondary Structure: The secondary structure of proteins and RNA refers to local folding patterns like alpha helices and beta sheets.
• Protein Misfolding: Protein misfolding can lead to the formation of abnormal structures and is associated with various diseases.
