Signal transduction and perception regulates biological activities to adapt to changing environments. The Pert-Arnt-Sim domains are commonly available sensors found across diverse receptors in bacteria, eukaryotes, and archaea. ...
Some fish come onto the land to hunt or move around. Typically, this behavior happens at nighttime, as seen in eels, for instance. In the new study, researchers have found that such amphibious fishes might have an enhanced ...

In biochemistry, a receptor is a protein molecule, embedded in either the plasma membrane or cytoplasm of a cell, to which a mobile signaling (or "signal") molecule may attach. A molecule which binds to a receptor is called a "ligand," and may be a peptide (such as a neurotransmitter), a hormone, a pharmaceutical drug, or a toxin, and when such binding occurs, the receptor undergoes a conformational change which ordinarily initiates a cellular response. However, some ligands merely block receptors without inducing any response (e.g. antagonists). Ligand-induced changes in receptors result in physiological changes which constitute the biological activity of the ligands.
