Delta function is required for bristle organ determination and morphogenesis in Drosophila

Article Abstract:

Studies of Delta (Dl) temperature-sensitive mutants show that reductions in Dl function during metamorphosis of Drosophila melanogaster can result in the multiplication or loss of bristle organs on the adult notum, based on the developmental interval during which such mutants are repulsed at controlled temperature. Dl function is necessary for cellular interactions crucial to the correct specification of supernumerary bristle first-order precursor (pI) cells inside proneural groups, and for morphogenesis of the bristle organ.

Male and female cooperate in the prohormone-like processing of a Drosophila melanogaster seminal fluid protein

Article Abstract:

The Drosophila melanogaster seminal fluid protein, Acp26Aa, is essential for the processing of Acp26Aa in the female genital tract and structurally represents a prohormone. Sequential proteolytic cleavage occur in the mated female during the processing, but no processing is observed during ectopic expression of Acp26Aa in the absence of mating. For proper processing function in the mated female, activities must be provided from the male.

Bifocal and PP1 interaction regulates targeting of the R-cell growth cone in Drosophila

Article Abstract:

Studies on Drosophila show that Bifocal regulates protein phosphatase-1 activity, and these two proteins foster proper axon targeting by influencing cytoskeleton dynamics in R cell growth cones.
