btl
Description

UASt regulatory sequences drive expression of a constitutively active form of btl in which the ligand-binding extracellular domain has been replaced with the dimerization domain of the bacteriophage λ cI repressor (to induce constitutive dimerization of the encoded protein).

Comments

report comment: Produces active form of btl with λ\cIDD dimerization domain; not dependent upon ligand-induced dimerization and thus results in constitutive activity. Regulated by UAS-binding species present.

(Lee et al., 1996)

construct_comment: Progenitors are those of the plasmid, pP{UAS-btl.λ}.See report for T:λ\cIDD.
