Protein Modification
Protein modification is a process in which specific proteins are altered via modification to achieve specific biochemical functions. The process may involve adding small protein molecules known as post-translational modifications (PTMs) to a protein, such as acetylation, methylation, and phosphorylation, or by larger modifications such as glycosylation. Protein modification is a key step in the regulation of most cellular activities, and an understanding of the mechanisms in which proteins are modified is essential for understanding the function of proteins within a cell. Protein modification also plays a critical role in many diseases, such as cancer, and is an important area of research in biochemistry and medical sciences. The utilization of specific protein modifications as biomarkers in clinical settings is important for the accurate diagnosis and prognosis of many different diseases. By understanding the processes by which proteins are modified, scientists can develop new drug targets for the treatment of many different diseases.
