Imprecise excision of the progenitor insertion, resulting in a 116bp deletion starting at position -33. The deletion removes part of exon 1 and the downstream intron. A 17bp footprint of the insertion (CATGATGAAATAA) remains at the original insertion site.
116 bp deletion resulting from the imprecise excision of P{EPgy2}Mob4EY23407. Reported as extending into the gene from the insertion site 33bp upstream of the Mob4 AUG.
Homozygotes and Mob4EYΔL307/Mob4EYΔL3 adults have a significantly reduced lifespan compared to controls.
Third instar mutant larvae have a "tail-flip" phenotype.
Mob4EYΔL307 third larval instar neuromuscular junctions show relatively normal synaptic depression during 10 Hz stimulation in 2mM extracellular Ca[2+] but complete failure in EPSCs are seen after 4 seconds with a faster 50Hz stimulation train.
