Cellular membrane protein

Cellular membrane proteins are a large, diverse group of proteins associated with the cell membrane, either embedded within the lipid bilayer (integral, transmembrane) or attached to its surface (peripheral, lipid-anchored)[1][2][3][6]. They serve critical roles in transport of molecules and ions, cell signaling, enzymatic activity, cell-cell recognition, and provide structural anchorage for the cytoskeleton and extracellular matrix[1][3][6]. Classification depends on their structural association with the membrane (transmembrane vs peripheral), topology (single-pass vs multi-pass), and functional family (receptors, transporters, channels, enzymes, adhesion molecules)[2][3][6][8]. They are central in physiology and disease, representing over half of all therapeutic drug targets, notably including G protein-coupled receptors, ion channels, and transporter proteins[4][7]. However, "Cellular membrane protein" is too broad for use as a single canonical molecular target, as it encompasses hundreds of specific therapeutic targets rather than a single entity. Key notes: - The entry "Cellular membrane proteins" is excessively broad and non-specific, referring to a superfamily rather than an individual target[3][4]. Therefore, the is_incorrect field is set to true. - For structured data, best practice is to assign individual canonical forms for each specific membrane protein, receptor, or transporter of interest, e.g., "Beta-2 adrenergic receptor," "Sodium-potassium ATPase," "P-glycoprotein", etc.
