signaling hormone neurotransmitter

SUBCELLULAR LOCALIZATION	extracellular
	intracellular

basic FUNCTION	involved in gallbladder contraction
	by separately regulating EGR1 activation and synthesis, CCK and leptin interact cooperatively to define the capacity for satiety signaling by vagal afferent neurons
