RT   species and functional insights into Crz-expressing neurons.";
RL   J. Comp. Neurol. 482:372-385(2005).
CC   -!- FUNCTION: Cardioactive peptide. Corazonin is probably involved in the
CC       physiological regulation of the heart beat. Clock (Clk) and cycle (cyc)
CC       proteins negatively regulate Crz transcription in a cell-specific
CC       manner (By similarity). {ECO:0000250|UniProtKB:Q26377}.
CC   -!- SUBCELLULAR LOCATION: [Corazonin]: Secreted
CC       {ECO:0000250|UniProtKB:Q26377}.
CC   -!- SUBCELLULAR LOCATION: [Corazonin precursor-related peptide]: Secreted
CC       {ECO:0000250|UniProtKB:Q26377}.
CC   -!- TISSUE SPECIFICITY: Expression is restricted to 24 neurons in the
CC       larval CNS (8 in the brain and 16 in the ventral nerve cord) and 12-16
CC       neurons in the pars lateralis of the adult brain.
CC       {ECO:0000269|PubMed:15669053}.
CC   -!- SIMILARITY: Belongs to the corazonin family. {ECO:0000305}.
