Under 12:12 light:dark zeitgeber cycles, trsnΔ homozygous mutants present increased average sleep time and decreased waking activity upon starvation conditions but not under normal diet conditions, as compared to wild-type controls; trsnΔ homozygous mutants do not show the starvation-induced sleep deprivation and increased waking activity observed in wild-type controls.
The compensatory increase in day-time sleep induced by mechanical night-time sleep deprivation observed in wild-type controls is not affected in trsnΔ homozygous mutant adults, as compared to controls.
Upon 24h starvation, trsnΔ homozygous mutant adults show similar intake of and similar proboscis extension reflex to either sugar-rich (sucrose solution) or protein-rich (yeast extract) tastants, as compared to controls; trsnΔ homozygous mutant adults also present unaltered food intake under either fed or starved conditions, as compared to controls under the same dietary conditions.
trsnΔ homozygous mutant adults present similar glycogen, triglyceride and free glucose levels under either fed and starved states, as compared to controls.
No differences in the rate of X chromosome nondisjunction are seen between trsnΔ/Df(2R)stan2 females and males and control flies.
trsnΔ/Df(2R)stan2 flies are not more sensitive to γ-irradiation than control flies.

trsnΔ is rescued by Scer\GAL4Lk.PK/trsnUAS.cMa
trsnΔ is rescued by Scer\GAL4nSyb.PS/trsnUAS.cMa
Expression of trsnScer\UAS.cMa under the control of either Scer\GAL4Lk.PK or Scer\GAL4nSyb.PS, in an trsnΔ homozygous mutant background, re-instates the starvation-induced sleep deprivation observed in wild-type controls.
