Approximately 7kb tant genomic fragment 1477bp of upstream and 3kb of downstream sequences.
Flies carrying two copies of tant7 in a wild-type background have defects in a variety of sensory tissues. Defects in the postvertical bristles include deletions, deletions with sockets remaining and reductions in size.
The effect of bristle number reduction, as seen in the N55e11/+; tan2/+ transheterozygotes can be alleviated by providing a single copy of tant7. The loss of interocellar bristles observed in Df(1)N-8/+; tan2/+ transheterozygotes can be rescued by a single copy of tant7 from 74.7% to 16.3% of flies exhibiting four or fewer interocellar bristles.

The loss of interocellar bristles observed in Df(1)N-8/+; tan2/+ transheterozygotes can be partially rescued by a single copy of tant7 from 74.7% to 16.3% of flies exhibiting four or fewer interocellar bristles. The loss of interocellar bristles observed in N55e11/+; tan2/+ transheterozygotes can be partially rescued by a single copy of tant7 from 26.7% to 4.1% of flies affected.
