PAG--a multipurpose transmembrane adaptor protein
1Institute of Molecular Genetics, Academy of Sciences of the Czech Republic, Prague, Czech Republic.
Abstract:
Phosphoprotein associated with glycosphingolipid-enriched microdomains (PAG), also known as Csk-binding protein (Cbp), is a ubiquitously expressed transmembrane adaptor protein present in lipid rafts and involved in a number of signaling pathways. It helps recruit cytoplasmic C-terminal Src kinase (Csk) to lipid raft-associated Src kinases, mediates a link to actin cytoskeleton and interacts with several other important cytoplasmic and plasma membrane-associated proteins. In recent years, PAG has been implicated in various aspects of cancer cell biology. Our review covers all so far published data on this interesting protein.

Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
