Early gene interaction during prepupal expression ofDrosophilaarginine kinase

摘要

AbstractArginine kinase displays a distinctive rise and fall in specific activity and specific protein levels during the prepupal stage ofDrosophiladevelopment with maximal activity occurring at morphological stage P3. This developmentally regulated peak is under the influence of ecdysone. Altered doses of the major ecdysone‐inducible “early” genes at cytological regions 75B and 2B5 alter this pattern of expression while altered doses of another major “early” gene at 74EF have no effect. We hypothesize that a product of the 2B5 locus and a product of the 75B locus interact to effect this developmental pattern of expression ofDrosophilaarginine kinase. © 1992 Wiley
