UASt sequences drive expression of a genomic fragment coding for amino acids 153-337 of the CkIα gene with the corresponding cDNA fragment inserted in a reverse orientation.
Expression of one copy of CkIαdsRNA.Scer\UAS under the control of Scer\GAL4Bx-MS1096 induces at most a few ectopic margin bristles on the wing, while expression of two copies results in the formation of numerous wing margin bristles on the wing.
The P{UAS-CkIα.CRL.dsRNA} construct provides a more efficient knockdown of CkIα than the P{UAS-CkIα.RNAi} construct.
This construct results in a specific knockdown of the CkIα gene.
