EOG880M9M GO:0043087 27/102 regulation of GTPase activity biological_process "Any process that modulates the rate of GTP hydrolysis by a GTPase." [GOC:jl, GOC:mah] EOG880M9M GO:0007269 1/102 neurotransmitter secretion biological_process "The regulated release of neurotransmitter into the synaptic cleft. A neurotransmitter is any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell. Among the many substances that have the properties of a neurotransmitter are acetylcholine, noradrenaline, adrenaline, dopamine, glycine, gamma-aminobutyrate, glutamic acid, substance P, enkephalins, endorphins and serotonin."

The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane."
