Tag: Membrane protein

The human body is composed of thousands of different proteins, all assembled from the same 20 amino acids but folded into unique three-dimensional shapes to perform a vast array of biological tasks. These essential macromolecules are broadly categorized into three main classes based on their structure, function, and solubility.

Protein 4.2 is one of the most abundant peripheral membrane proteins found in the erythrocyte, or red blood cell, membrane, making up approximately 5% of its total protein content. This vital protein acts as a crucial linker, connecting the membrane skeleton to the lipid bilayer, ensuring cell stability.
