Frameshift mutation: base pairs 12-16 of the coding sequence have been deleted and substituted with TTGGTCGTCTATTGG. This is predicted to result in a truncated protein of 33 amino acid residues.
The deletion of 5 base pairs and insertion of 15 (TTGGTCGTCTATTGG) leads to a frameshift and early translation terminaion.

STUB1II mutant adults exhibit reduced climbing ability along with age-progressive mitochondrial defects (decreased thoracic mtDNA content and disorganization of the cristae).
STUB1II/STUB1II is a non-enhancer of abnormal locomotor behavior | adult stage phenotype of parkΔ21/park1
STUB1II/STUB1II is a non-suppressor of abnormal locomotor behavior | adult stage phenotype of Pink1B9
The reduced climbing ability of park1/parkΔ21 mutants is not exacerbated by combination with STUB1II in homozygous state, but the lifespan of the double mutants is significantly decreased compared to park1/parkΔ21 single mutants. Similarly, the climbing deficit observed in Pink1B9 mutants is also not exacerbated by combination with STUB1II in homozygous state; lifespan of the double mutants is not significantly different from the Pink1B9 single mutants.
