EOG82586J GO:0005089 29/101 Rho guanyl-nucleotide exchange factor activity molecular_function "Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase." [GOC:mah] EOG82586J GO:0046928 1/101 regulation of neurotransmitter secretion biological_process "Any process that modulates the frequency, rate or extent of the regulated release of a neurotransmitter from a cell." [GOC:ai] EOG82586J GO:0035011 1/101 melanotic encapsulation of foreign target biological_process "Formation of a multilayered, melanized sheath of cells around a foreign invader." [GOC:bf] EOG82586J GO:0007480 1/101 imaginal disc-derived leg morphogenesis biological_process "The process in which the anatomical structures of a leg derived from an imaginal disc are generated and organized. A leg is a limb on which an animal walks and stands. An example of this is found in Drosophila melanogaster." [GOC:mtg_sensu, ISBN:0879694238] EOG82586J GO:0031594 1/101 neuromuscular junction cellular_component "The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential." [GOC:nln] EOG82586J GO:0016740 1/101 transferase activity molecular_function "Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2." [ISBN:0198506732]
