Cytology

Description

Mutated tam at the endogenous locus: carries a mutation in a highly conserved residue (amino acid replacement Q1009A). Generated by re-integration of DNA into the attP site present in tam^KO. Additional sequences inserted during the re-integration event are also present: 1. a loxP cassette containing the w^GMR.PHb marker, upstream of tam, 2. a single attR site, downstream of tam.

Nucleotide change:

CAG13824553GCG

Reported nucleotide change:

CA?GC

Reported amino acid change:

Q1009A

Comment:

CA to GC nucleotide change leads to a Q1009A mutation in the reintroduced copy of the PolG1 gene at the endogenous site.

Phenotype Manifest In

Detailed Description

Statement

Reference

tam^Q1009A/tam^Q1009A mutants die in the third instar stage and exhibit significantly lower body weight, as compared to controls.

tam^Q1009A/+ flies do not exhibit a significant increase in mtDNA mutation frequency, as compared to wild type. tam^Q1009A/tam^Q1009A, but not tam^Q1009A/+, mutants exhibit a severe reduction in mtDNA levels, as compared to wild type.

tam^Q1009A/tam^D263A flies do not exhibit any significant difference in body weight or mtDNA levels as compared to controls, but offspring of tam^Q1009A/tam^D263A mothers exhibit a significant developmental delay.

tam^KO/tam^Q1009A and tam^KO/tam^H1038A mutants exhibit lethality, with most individuals dying in the third instar larval stage, and the remainder dying during pupal stage; and larvae exhibit a significant decrease in body weight, as compared to controls.

tam⁴/tam^Q1009A and tam³/tam^Q1009A mutants exhibit complete lethality.
