Sequence and structure conservation in yolk proteins and their genes

摘要: Abstract The yp 1 and 2 genes of Drosophila code for egg yolk proteins. Their transcription is hormone-dependent co-ordinate. In this paper we describe the complete nucleotide sequence gene region between these two divergently transcribed genes. We also map mature messenger RNA on sequence. then use information similar previously determined to find features common Most sequences flanking are consensus that have been found in many other eukaryotic An unusual feature a potential stem-and-loop structure, which has TATA box capping site, ribosomal homology translation initiation codon at four successive junctions single strands duplexes. A second 13-nucleotide recently proposed progesterone-receptor binding site. speculate structure conserved may be involved co-ordinate, expression examining proteins 53% homologous predicted secondary structures nearly identical. propose important oligomerization perhaps activities
