The proteins of polytene chromosomes of Drosophila hydei
Chromosoma, 1975It is reported that chromatin can be prepared from highly purified polytene nuclei from the salivary glands of third instar larvae of Drosophila hydei; such chromatin differs from that of diploid nuclei mainly by deficiencies in certain nonhistone chromosomal proteins.

The GAGA Protein of Drosophila is Phosphorylated by CK2
Journal of Molecular Biology, 2005The GAGA factor of Drosophila is a sequence-specific DNA-binding protein that contributes to multiple processes from the regulation of gene expression to the structural organisation of heterochromatin and chromatin remodelling. GAGA is known to interact with various other proteins (tramtrack, pipsqueak, batman and dSAP18) and protein complexes (PRC1 ...

Scaffolding Proteins at the Drosophila Neuromuscular Junction
2006Publisher Summary This chapter discusses the genetic approaches that have been used at the Drosophila neuromuscular junction (NMJ) to elucidate the in vivo significance of scaffolding proteins for synaptic structure and function. Scaffolding molecules are commonly found in association with the cytoplasmic face of membrane specializations such as ...

In, vitro studies of protein synthesis in Drosophila
Biochemical and Biophysical Research Communications, 1969Abstract Comparative in , vitro studies of protein synthesis in Oregon-R wild-type and A 53g mutant Drosophila , melanogaster indicate that the A 53g genotype has an effect at the translation level. The A 53g post-microsomal supernatant fluid stimulates the incorporation of C14 amino acids by cell ...

The transcriptional regulation of PER protein in Drosophila
Journal of Theoretical Biology, 2019We propose an auto-activation model controlled by a negative feedback transcriptional regulator to describe the circadian rhythm in Drosophila melanogaster. The model is specific to eukaryote organisms and oscillations are induced by a two-compartment approach, the nucleus and the cytoplasm.

A gradient of bicoid protein in Drosophila embryos
Cell, 1988The maternal gene bicoid (bcd) organizes anterior development in Drosophila. Its mRNA is localized at the anterior tip of the oocyte and early embryo. Antibodies raised against bcd fusion proteins recognize a 55-57 kd doublet band in Western blots of extracts of 0-4 hr old embryos.

The Drosophila homologue of ribosomal protein L8
Insect Biochemistry and Molecular Biology, 1999We have cloned the gene encoding the Drosophila melanogaster homologue of ribosomal protein L8. It contains two introns: one in the 5' untranslated region and the second in the beginning of the ORF, and encodes a 256-residue protein which is highly conserved when compared with RpL8 proteins of other organisms.

Identification of a Drosophila 60S ribosomal protein
Insect Biochemistry and Molecular Biology, 1997We have previously reported the cloning and sequencing of a cDNA from Drosophila (DL43; GenBank Accession # U40226) which predicts a small protein homologous to a ribosomal protein in yeast and rat. In this study we show that a 330 nucleotide transcript encoding the putative ribosomal protein is expressed in Drosophila Kc cells under normal growth ...

Evolution of protein-coding genes in Drosophila
Trends in Genetics, 2008Several contributing factors have been implicated in evolutionary rate heterogeneity among proteins, but their evolutionary mechanisms remain poorly characterized. The recently sequenced 12 Drosophila genomes provide a unique opportunity to shed light on these unresolved issues.

Protein Extraction From Drosophila Heads
2007In Drosophila, the concentration and phosphorylation levels of several important circadian proteins (e.g., PERIOD, TIMELESS) oscillate on a 24-h basis. A simple and rapid method for extracting proteins from fly heads is presented here. The extracts can immediately be loaded onto an sodium dodecyl sulfate-polyacrylamide gel electrophoresis gel to assay ...
