Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
In a sample of 79 genes with multiple introns, 33 showed significant heterogeneity in G+C content among introns of the same gene and significant positive correspondence between the intron and the third codon position G+C content within genes. These results are consistent with selection adding against preferred codons at the start of genes.
Sgs5 encodes a salivary-gland glue protein. One of a group of seven genes encoding proteins that are components of the secretion produced by the larval salivary glands during the third instar for the purpose of attaching the larva to the substrate preparative to pupariation.
Sgs3, Sgs4 and Sgs5 transcript levels were very low in hemizygous brrbp-1 larvae and pupae.
Cessation of Sgs5 transcription and puff regression are ecdysterone-dependent.
Initiation of transcription of Sgs5, but not of intermolt-puff formation seems to depend on the presence of suitable levels of ecdysterone in early third instar larvae.
Synthesis of the glue proteins begins about 106 h after egg deposition and ceases abruptly within a few minutes after the glue is released 14 h later.
