Gcn2 transcripts are detected throughout development and are particularly abundant in early embryos.
Gcn2 transcripts are expressed throughout development as revealed by northern blots with peaks in 0-12hr embryos, third instar larvae, and adults. High levels of Gcn2 transcripts are first detected by in situ hybridization in stages 2 and 3 prior to cellularization. In late stage 4 and stage 5, transcripts are concentrated in the cortex. By gastrulation, expression is concentrated at areas of cell movement, including all the furrows and the proctodeal primordium. During germ band extension, expression occurs in primordia of the anterior and posterior midguts and in the mesoderm. By the end of stage 12, transcripts accumulate in the anterior and posterior midgut and in areas of the primitive brain and the CNS. By stage 13, Gcn2 transcripts are observed throughout the CNS including the supraesophageal ganglion and the ventral nerve cord. In later stages, the CNS expression is restricted to 4 cells per neuromere which are probably neurons.

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.
