The axon initial segment (AIS) is the specialized compartment of vertebrate axons where action potentials are initiated. Despite longtime attention to the unique functions of this compartment, the mechanisms that regulate AIS formation and maintenance are not known. Here, we identify a novel compartment in Drosophila mushroom body neurons that mirrors the(More)
Synaptic transmission depends on the matching and alignment of presynaptically released transmitters and postsynaptic neurotransmitter receptors. Neuroligin (NL) and Neurexin (Nrxn) proteins are trans-synaptic adhesion molecules that are important in validation and maturation of specific synapses. NL isoforms NL1 and NL2 have specific functional roles in(More)
