Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
brp1.3 mutants exhibit significantly reduced survival rates and motor abilities.
In brp1.3 mutants, with poorly clustered Ca[2+] channels, the EPSC amplitudes are reduced to approximately 30% of control amplitudes, The amplitude of miniature EPSCs is not significantly affected.
Depression decay during paired-pulse stimulation is stronger in brp1.3 mutants, compared to controls. Consistent with the altered paired-pulse ratio, the amplitude of the second EPSC in the train is also significantly reduced.
brp1.3 mutant synapses display enhanced depression during sustained high frequency transmission. Consistently, both the first and second components of recovery are slower.
T bar-like structures are seen at the neuromuscular junction in mutant third instar larvae, although they typically appear shortened and are observed at a lower frequency than in controls.
