Gene Summary
Corazonin (Crz) encodes a neuropeptide expressed in specific groups of neurons. It functions as a neurohormone and neuromodulator, which involves a G-protein-coupled receptor. Its roles include ethanol and trehalose metabolism, and male reproductive activity. [Date last reviewed: 2019-03-07] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
NEUROPEPTIDES -
Neuropeptides are secreted into the extracellular space where they interact with cell surface receptors (usually G protein coupled receptors). They are extremely diverse, acting as neurotransmitters, neuromodulators, hormones or growth factors. (Adapted from FBrf0211443 and PMID:27813667).
Protein Function (UniProtKB)
Cardioactive peptide. Corazonin is probably involved in the physiological regulation of the heart beat. Clock (Clk) and cycle (cyc) proteins negatively regulate Crz transcription in a cell-specific manner.

Additional Descriptive Data

Crz colocalizes with Scer\GAL4ATP7.PB expressing interneurons in the larval abdominal neuromere.

Crz is observed in 2 pairs of interneurons in the abdominal ganglion. Expression co-localises with that of Scer\GAL4Crz.391.

Crz is expressed in the peptidergic CC-LP2 neurons in the larval brain.

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.

Co-localisation of Crz and Scer\GAL4dimm-929 is observed in a subset of Crz-positive neurons of the central nervous system.

Markers that uniquely identify the cells of the NB3-7 lineage were used to examine the serotonin expressing cell lineages.

          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.
