Description

A single nucleotide deletion in the P32 ORF resulting in a premature stop codon that truncates the protein after 101 amino acids. "C" at position 303 is deleted, and thus the resulting codon change is from "GCC GTA A" to "GCG TAA".

Detailed Description
Statement
Reference

P32EC1/P32EC1 or P32EC1/Df(2R)14F06W-07 flies are paralysed rapidly at 38[o]C.

P32EC1 flies show a heat-sensitive reduction in the excitatory postsynaptic current amplitude.

DLM neuromuscular synapses of P32EC1 flies at the restrictive temperature show proper transport and localization of pre-synaptic mitochondria.

At both 20[o]C and the restrictive temperature of 36[o]C, P32EC1 flies exhibit a wild type mitochondrial membrane potential.

ATP measurements on head homogenates from P32EC1 flies exposed to the restrictive temperature of 38[o]C indicate no significant difference from controls.

At the restrictive temperature, the presynaptic calcium transients elicited by 40 Hz stimulation is increased in the DLM neuromuscular synapses of P32EC1/Df(2R)14F06W-07 flies compared to controls. Resting presynaptic calcium is also increased in the mutant flies at elevated temperatures.

Statement
Reference

Unlike cacTS2 alone, cacTS2 P32EC1 double mutants exhibit rapid paralysis at 36[o]C.

P32EC1 strongly enhances the cacTS2 synaptic transmission phenotype.

There are no obvious changes in basic synapse morphology in cacTS2 P32EC1 double mutants.
