Cecropin mRNAs are induced after injection of a bacterial suspension into adult abdomens. They can also be induced by feeding flies bacteria-containing food.
CecB transcripts are only detected in untreated animals in small amounts in early pupae and adults. They are strongly induced by bacteria. CecB transcripts are preferentially induced in early pupae as opposed to larvae or adults. CecB levels are lower than CecA in fat body and comparable in hemocytes.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
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.
Source for identity of: CecB CG1878
Identified as a gene with significant level of mRNA cycling as assessed by expression analysis using high density oligonucleotide arrays with probe generated from adult heads harvested over six time points over the course of a day. Shows alteration in expression in a Clk mutant background.
One of four structural genes for four very similar cecropin proteins (cecropin A1, A2, B and C), bacteriocidal proteins that are induced in adults in response to bacterial infection. All cecropin genes are coordinately induced by injection of bacteria, although the B gene is expressed at a much lower level. Cecropins also induced by ingested bacteria.
