Cellular proteomics is a scientific discipline that explores the expression, modification, interaction, and function of all proteins within cells. As a significant branch of proteomics, the development of cellular proteomics is closely linked to the progress of proteomics itself. In 1995, the term "proteomics" was introduced, marking the official start of proteomics research. With advancements in mass spectrometry technology, studies on intracellular proteins became increasingly sophisticated.
