A Cell Signaling

Which one of the following lipid-soluble hormones can interact with a cell surface receptor?

Prostaglandin, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.

Cell Signaling Fundamental Principles

Cell surface receptors mainly bind

Hydrophilic ligands cannot cross the plasma membrane and therefore bind cell-surface receptors that transmit the signal into the cell. Hydrophobic ligands such as steroid hormones readily diffuse across the bilayer and bind intracellular receptors that often function as ligand-activated transcription factors. This physicochemical distinction dictates the location and primary mechanism of receptor action.
