Encoded product / tool
htl
Description

UASt regulatory sequences drive expression of an activated form of htl in which the extracellular domain of htl has been replaced with the dimerization domain of the bacteriophage λ cI repressor (to induce constitutive dimerization of the encoded protein).

Comments

construct_comment: See report for T:λ\cIDD.

(Michelson et al., 1998)

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