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.

Two categories of cationic lipids emerge from the cationic lipid-induced activation of cellular cascades. Cationic lipids that activate TLR-dependent pathways and seem to satisfy specific structural requirements of TLR4 for LPS-like ligands and cationic lipids with a broader specificity, that activate CD80/86 expression at the cell surface but not NF-κB and cytokine secretion.We propose that knowledge of specific phosphorylations might be used to develop pharmacological peptides to fine-tune the Nem1-Spo7/Pah1 phosphatase cascade and lipid synthesis in vivo. Furthermore, such an approach might be applicable to higher eukaryotes owing that this cascade and its regulation by phosphorylation is conserved.

The lipid transfer domain of LTPs is highly specific; often it can bind two different lipids allowing for lipid exchange to take place. Another important aspect of lipid biosynthesis is the side (leaflet) of the bilayer that the lipid is synthesised. Lipid synthesis often requires the movement of a lipid from one leaflet to the other.
