Protein transport refers to the process by which proteins are transported within and between different cellular compartments of an organism. This includes the movement of proteins from their site of synthesis in the cytoplasm to other organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and cell membrane. Protein transport is essential for regulating various cellular processes, including cell signaling, energy production, and cell growth. Dysregulation of protein transport can lead to various diseases, such as neurodegenerative disorders and metabolic syndromes. Research in the field of protein transport explores the mechanisms and molecular machinery responsible for protein trafficking within cells, and how disturbances in these processes contribute to disease pathology. By understanding protein transport, researchers aim to develop new treatments and therapies for a range of human diseases.
