An imprecise excision retaining 23 bp of the progenitor P{lacW}srpk79DP1 that deletes 3861 bp of the srpk79D locus downstream of the progenitor insertion site.
3861 bp deletion resulting from the imprecise excision of P{lacW}Srpk79DP1, which removes the transcription and translation starts of many of the Srpk79D transcripts and the first 85 amino acids of the SR kinase domain. 23 bp of the P element remain at the site of the excision.
General axonal transport and basic synaptic structure and function appear intact in srpk79DVN100 mutants.
srpk79DVN100 mutant larval nerves display larger and more numerous electron-dense ribbon structures resembling T-bars of presynaptic neuromuscular boutons than wild-type controls.
srpk79DVN100 mutant flies display flight impairment, reduced ability or motivation to walk on a horizontal surface, as well as reduced life span.
