This research aims to examine the interplay between potassium currents and neuromuscular transmission in Drosophila mutants.
Utilized recombinational dissection of the ShrK0120 strain of Drosophila melanogaster.
Conducted complementation tests with various Sh and eag alleles to assess neuromuscular transmission defects.
Performed pharmacological experiments using potassium channel blockers 4-AP and TEA.
The ShrK0120 strain showed prolonged neuromuscular transmission due to a synergistic interaction with a second mutation.
Motor axons exhibited spontaneous repetitive firing and increased neurotransmitter release in double mutants.
Distinct effects were observed with Sh and eag mutations affecting different potassium currents.
