Cellular localization is the study of where specific molecules, proteins, or organelles are located within a cell. This research area aims to understand the spatial organization of cellular components and how their localization influences cellular processes and functions. Techniques such as immunofluorescence microscopy, electron microscopy, and live-cell imaging are commonly used to study cellular localization. By determining the precise location of molecules within a cell, researchers can gain insights into how cells function and communicate with each other. This information is important for understanding various biological processes, such as cell signaling, gene expression, and cell division.
