Chromosomal rearrangement in the Sh region.
Involves a chromosomal rearrangement in the Sh region.
Probably an inversion with breakpoints in centric heterochromatin and within Sh (FBrf0047308).
Probably an inversion with breakpoints in centric heterochromatin and 16F.
break at 61; relative to the Sh chromosomal walk in kb (Kamb, Iverson and Tanouye, 1987)
Muscle fibres and photoreceptors have no detectable IA (rapidly inactivating A current).
Mutant photoreceptors lack the most inactivating A-current (IA).
IA is completely eliminated in homozygous third larval instar muscles.
Fails to produce functional A-channel and does not interact with wild type Sh protein.
abnormal leg shaking under ether anesthesia; abnormal A-type potassium currents in larval muscle and/or pupal flight muscle
