Description

Amino acid replacement: W273term.

(Crompton et al., 1995)

The premature stop codon is in exon G of shakB and is predicted to result in a truncated protein that lacks the C-terminal 100 amino acids of the wild-type protein.

(Crompton et al., 1995)

Nucleotide substitution: G1657A.

(Crompton et al., 1995)

Mutation in the lethal and neural common exons. Amino acid replacement: W262@. Nucleotide substitution: TGG to TGA. Residue lies in the membrane-spanning domain.

      Lethal and neural allele. Fails to complement the giant fibre system defects of viable shakB alleles.

      (Crompton et al., 1995)

      The DLMs do not respond to brain shocks and the TTMs respond only occasionally and then with a longer than normal latency.

      (Krishnan et al., 1995)

      Abnormal electrophysiological phenotype. Homozygous flies exhibit uncoordinated leg movements under ether anaesthesia and do not jump to a light off stimulus. Heterozygotes are fully viable but exhibit some neuronal defects.

      (Baird et al., 1990)

      Homozygous germline clones display no maternal effect.

      (Perrimon et al., 1989)

      shakB22/shakB2 flies show shaking behaviour.

      Maternal germline clonal analysis demonstrates there is no maternal effect.

      (Perrimon et al., 1989)

      shakB alleles exhibit a complex pattern of complementation.
