Description

Lesion within the ttm50 coding sequence that results in a new stop codon. This is predicted to result in a truncated protein of 31 amino acid residues.

Comment:

A 5bp deletion in ttm50 affecting codons 28-30 causes a frameshift and leads to early translation termination after the addition of 3 novel amino acids.

      ttm50CRISPR clones in mosaic early third instar larval fat bodies show small cells that accumulate autophagosome-like structures (Atg8a-positive) wrapping ubiquitinated protein aggregates, as compared to controls.

      ttm50CRISPR clones in mosaic eyes show loss of rhabdomeres/neurodegeneration, as compared to controls.
