Description

Genomic fragment containing usp with a mutation that disrupts an amino acid (Q288A) that normally extends a side chain into the ligand binding pocket, resulting in a usp protein with reduced affinity for the methyl farnesoate ligand.

Detailed Description
Statement
Reference

uspQ288A usp2 animals progress normally through to apolysis of the the epidermis away from the cuticle (albeit with a briefly longer 3rd instar feeding stage compared to normal larvae). Subsequently, uspQ288A usp2 animals do not form a normal puparium - it is dorso-ventrally flattened, the partially everted anterior spiracles point directly forward, the cuticle is only faintly sclerotized, the 'puparial' cuticle is transparent rather than brown, and head eversion is incomplete. Most animals stop development during the early pupal stage and eventually die.

uspQ288A partially rescues usp2

Comments

uspQ288A rescues usp2 first instar larval lethality to the prepupal stage: larvae progress normally through to apolysis of the the epidermis away from the cuticle (albeit with a briefly longer 3rd instar feeding stage compared to normal larvae). Subsequently, uspQ288A usp2 animals do not form a normal puparium and most animals stop development during the early pupal stage and eventually die.
