Membrane Protein Knowledge

Membrane proteins can be broadly classified based on their structure and positioning within the cell membrane. The primary categories include integral (intrinsic) proteins, peripheral (extrinsic) proteins, and lipid-anchored proteins.

Membrane protein biosynthesis and trafficking are coordinated processes. Proteins start synthesis in the cytoplasm, move to the endoplasmic reticulum for folding and modifications, and are then transported to specific destinations via vesicles. Studying this pathway helps understand cellular dysfunctions from mistargeted or misfolded proteins.
