NotI-XhoI fragment of genomic DNA approximately 20kb in size that contains the Kap3 gene. Position of restriction fragment on reference sequence inferred by FlyBase curator.
Kap3+t20 rescues the odor-evoked electroantennogram response in Kap3V5 and Kap3V6 animals (assayed in response to ethyl acetate, n-butanol, benzaldehyde and propionic acid).
