We identified a unique type II cAMP-dependent protein kinase regulatory subunit (PKA-RII) gene in Drosophila melanogaster and a severely hypomorphic if not null mutation, pka-RII(EP(2)2162). Extracts from pka- RII(EP(2)2162) flies selectively lack RII-specific autophosphorylation activity and show significantly reduced cAMP binding activity, attributable to(More)
The asteroid gene of Drosophila was found to lie within 189 bp of Star. Asteroid cDNA clones were isolated and sequenced and a single putative open reading frame was identified that encodes a novel protein of 815 amino acids with a calculated molecular mass of 93 kilodaltons. Using cDNA probes, asteroid transcripts were localized to the proliferative(More)
