open position of a ligand-gated ion channel, where ions are able to pass through across the membrane
effector protein that produces the second messenger cyclic AMP (cAMP) during cell signaling
second messenger molecule that regulates many different metabolic functions. It is found in nearly every organism.
union of two molecules, such as receptor tyrosine kinase molecules, which forms in response to receiving a signal
receptor that works in conjunction with G protein, which uses guanosine triphosphate (GTP) to activate an ion channel or an enzyme
receptor that acts as a gate, allowing ions into or out of the cell when a signaling molecule binds
membrane receptor kinase that phosphorylates (adds a phosphate group to) the amino acid tyrosine of a substrate protein. Its action can lead to many different cellular responses.
small molecule, such as cyclic AMP (cAMP), that carries a message from a membrane receptor into the cytoplasm or may not use the membrane receptor at all
receptor that acts as a gate, allowing ions into or out of the cell in response to a change in electrical charge across the membrane
