UASt regulatory sequences drive expression of a C-terminally truncated form of Hsap\MYBPC3 (lacks the C5-C10 domains) which is tagged with Tag:MYC.
This construct encodes a truncated protein comparable to the MYBPC3 c.1928-2A>G variant, which occurs in a canonical splice acceptor site, resulting in exon skipping and premature termination.
Flies expressing Hsap\MYBPC3M0.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4sd-SG29.1 are flightless and hold their wings in abnormal position compared to wild type. The severity of the phenotype is age- and dose-dependent. 15 day old flies carrying two copies of Hsap\MYBPC3M0.Scer\UAS.T:Hsap\MYC show distortion of the Z-band in indirect flight muscles. Deformation of the M-line is occasionally seen and the I-band appears stretched and disorganised. The sarcomeres are approximately 10% shorter on average than in control flies.
Hsap\MYBPC3M0.UAS.Tag:MYC, Scer\GAL4sd-SG29.1 has flightless phenotype, suppressible | partially by Cam[+]/Cam03909
Hsap\MYBPC3M0.UAS.Tag:MYC, Scer\GAL4sd-SG29.1 has flightless phenotype, suppressible | partially by Cam[+]/Camk04213
Heterozygosity for either Camk04213 or Cam03909 partially rescues the flightless phenotype caused by expression of Hsap\MYBPC3M0.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4sd-SG29.1.
