The gene Corazonin is referred to in FlyBase by the symbol Dmel\Crz (CG3302, FBgn0013767). It is a protein_coding_gene from Drosophila melanogaster. It is reported to have molecular function: neuropeptide hormone activity. It is reported to be involved in the biological process: neuropeptide signaling pathway. 3 alleles are reported. No phenotypic data is available. It has one annotated transcript and one annotated polypeptide. Protein features are: Procorazonin. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of extremely low expression. Peak expression observed within 18-24 hour embryonic stages, during early larval stages, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval/adult central nervous system. Expression at moderate levels in the following post-embryonic organs or tissues: adult head. Comments on Affy2 ProbeSet: ProbeSet 1641343_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Crz. Gene sequence location is 3R:10140576..10141438.

Expression of Crz is expressed in a group of neurons that the authors call the DM ('Dorsomedial') and DL ('Dorsolateral') neurons in the protocerebrum, and the eight bilaterally symmetric 'vCrz' neurons of the ventral nerve cord.
Expression of Crz protein is seen within three pairs of neurosecretory cells located close to the Kenyon cells of the third instar larvae. These cells send projections to the ring gland and also express Scer\GAL4NP6301. In the adult brain, expression of Crz protein is seen in a small group of neurosecretory cells in the dorsal protocerebrum called DLN1s.

The EcR-A isoform is not a signal transducer for programmed cell death in Crz-expressing ventral nerve cord neurons. EcR-B isoforms play significant roles in Crz-expressing ventral nerve cord neuron cell death.
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.
