Proteins and Membranes

The term Proteins and Membranes refers to the fundamental structural and functional assembly of cellular lipid bilayers and their associated protein molecules. It is not a specific therapeutic target, but rather a broad biological category encompassing integral, peripheral, and lipid-anchored proteins that facilitate essential processes such as signal transduction, ion transport, and cell-to-cell communication (Alberts et al., 2014). While approximately 60% of current drug targets are membrane-bound proteins, the collective term is too non-specific for drug discovery or clinical application (Santos et al., 2017). Because this category includes thousands of distinct proteins with divergent functions, it cannot be linked to a single disease state or mechanism of action. Instead, it serves as the physiological context for various specific target classes, including G protein-coupled receptors (GPCRs), ion channels, and transporters. In a therapeutic context, identifying a target as Proteins and Membranes is considered incorrect due to the lack of a discrete molecular entity that can be modulated by a pharmacological agent. Effective drug development requires the identification of specific subunits or isoforms within this broad category to ensure efficacy and minimize off-target toxicity.
