Module 4: Figure membrane and protein trafficking

Membrane and protein trafficking pathways.

The turnover of membrane components and proteins depends on a constant flux between the plasma membrane and an array of intracellular organelles such as the endoplasmic reticulum, Golgi, various endosomal compartments and the lysosome. The lipid signalling pathways responsible for controlling these trafficking processes is described in Module 2: Figure localized inositol lipid signalling. The major pathways that connect these different organelles are described in the text. CI-MPR, cation-independent mannose 6-phosphate receptor.
