Abstract:
Caveolae are small invaginations of the plasma membrane found in a variety of cells. The major components of caveolae are cholesterol, sfingolipids and structural proteins named caveolins. Three caveolin isoforms are known: caveolin-1, caveolin-2 and caveolin-3. Adipocytes, endothelial cells, pneumocytes and fibroblasts express caevolin-1 and-2, whereas caveolin-3 expression is limited to muscle cells types. Caveolae and caveolins have diverse functions including vesicular transport, cholesterol homeostasis, signal transduction or tumor suppression. The aim of the present review is to explain what is known about caveolae and caveolins.

Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the anterior...

Coat Assembly and GTPases
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...
