Protein modification

Protein modification refers to the process where proteins undergo specific chemical changes after they are produced. These modifications, such as adding phosphate groups or sugar molecules, can alter a protein’s activity, stability, location within the cell, or interactions with other molecules. This regulation ensures proteins function correctly and respond to the cell’s needs. Modifications can be temporary or permanent and are essential for proper cell operation, growth, and response to signals. Overall, protein modification is a crucial way cells fine-tune their functions and maintain health.
