Lipid cascade.

Although lipid signaling is implicated in diverse biological functions, its importance in synaptic mechanisms has become increasingly evident (1 -3).In the first step of lipid signaling, phospholipase A 2 (PLA 2) acts on membrane phospholipids to release arachidonic acid (AA) and certain lysophospholipid mediators.We previously reported that, among the more than 20 PLA 2 subtypes so far ...

Cell-surface receptors are membrane-anchored proteins that bind to ligands on the outside surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands.

The signal that starts the MAPK/ERK pathway is the binding of extracellular mitogen to a cell surface receptor.This allows a Ras protein (a Small GTPase) to swap a GDP molecule for a GTP molecule, flipping the "on/off switch" of the pathway.
