Cellular and subcellular structures

Cellular and subcellular structures refer to the organized, specialized components within a cell, including the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and the cytoskeleton (Alberts et al., 2002, Molecular Biology of the Cell). These structures are essential for maintaining life, as they provide the spatial organization required for complex biochemical processes such as DNA replication, ATP synthesis, and protein trafficking (Cooper, 2000, The Cell: A Molecular Approach). While these compartments contain the vast majority of known therapeutic targets, such as receptors and enzymes, the structures themselves are not considered discrete drug targets. For example, while a drug may target a specific protein on the mitochondrial membrane, the mitochondrion as a whole is a biological category rather than a single druggable entity (NCBI, 2023, Cell Biology). Consequently, this term is too broad for specific drug discovery applications and does not represent a single molecular target. It serves as a high-level classification for the locations where biological activity and drug interactions occur.
