Abstract:
The existence of plasma-membrane-raft microdomains has been widely debated during the past few years. However, it is clear that during lymphocyte stimulation a lipid-based reorganization occurs at the plasma membrane, with markers of the membrane rafts being selectively recruited to key active regions of the cell. Recent reports have demonstrated that membrane-raft dynamics are controlled by proteins that are linked to the actin cytoskeleton and have suggested a new model for the plasma membrane based on protein-lipid interactions. This new and dynamic view of the plasma membrane may improve our understanding of the complex process leading to cell polarization during lymphocyte migration and activation.

Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...
Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
