ProteostaseModifikation

ProteostaseModifikation refers to the dynamic regulatory processes that control the abundance and function of proteins within a cell. It encompasses a range of mechanisms, including protein synthesis, degradation, and post-translational modifications. These modifications ensure that the cellular proteome, the complete set of proteins expressed by a cell or organism, is precisely maintained and responsive to changing cellular conditions and environmental cues.

Key to proteostasis are pathways that regulate protein synthesis, such as the stringent control of gene expression and translation. Equally important are mechanisms that eliminate damaged or misfolded proteins, primarily through the ubiquitin-proteasome system and autophagy. Post-translational modifications, like phosphorylation, ubiquitination, and acetylation, further fine-tune protein activity, localization, and stability.

Disruptions in proteostasis are implicated in a variety of diseases, including neurodegenerative disorders like Alzheimer's and Parkinson's disease, as well as cancer and metabolic disorders. Maintaining proteostatic balance is therefore crucial for cellular health and organismal well-being. Research into proteostasismodifikation aims to understand these intricate regulatory networks and to identify potential therapeutic targets for diseases associated with proteostatic dysfunction. The study involves a multidisciplinary approach, integrating biochemistry, molecular biology, genetics, and cell biology.
