Additional Descriptive Data

Expression in stage P3 pupal leg discs is restricted to presumptive tarsal joints.

RhoGAP100F transcript is expressed in the embryonic central nervous system. In the adult, it is found throughout the brain, co-localising with the presynaptic marker brp. In the mushroom bodies, RhoGAP100F is found opposite the postsynaptic acetylcholine receptor nAChRalpha7. In the larva, it is found in the presynaptic active zone of the neuromuscular junction, where it forms clusters surrounding the centre of the active zone as defined by brp. In these clusters it co-localises closely with Liprin-α.

    Loss of RhoGAP100F function disrupts two distinct phases of presynaptic development in the R7 photoreceptor cell axons, resulting in two phenotypes: termination before the M6 medulla target layer, and projection of extensions beyond the M6 medulla layer.
