Protein regulation involves various processes that control the synthesis, modification, and degradation of proteins within a cell. Key mechanisms include:
• Transcriptional Regulation: Controls the production of mRNA from DNA, thereby influencing how much protein is synthesized.
• Translational Regulation: Affects how mRNA is translated into protein, impacting the rate of protein synthesis.
• Post-Translational Modifications: Involves changes to the protein after it is synthesized, such as phosphorylation, acetylation, or ubiquitination, which can alter its activity, stability, or localization.
• Protein Degradation: Regulates the lifespan of proteins through systems like the ubiquitin-proteasome pathway or autophagy.
