CC -!- FUNCTION: Ligand for the CCHamide-2 receptor CCHa2-R (PubMed:23293632, CC PubMed:21110953). In one study, shown to be an orexigenic peptide which CC induces appetite and stimulates food intake, leading to the release of CC insulin-like peptides which stimulate growth (PubMed:26168160). In CC another study, shown to be a nutrient-sensitive peptide derived from CC peripheral tissues which controls growth by directly regulating the CC production and release of insulin-like peptides (PubMed:26020940). CC {ECO:0000269|PubMed:21110953, ECO:0000269|PubMed:23293632, CC ECO:0000269|PubMed:26020940, ECO:0000269|PubMed:26168160}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}. CC -!- TISSUE SPECIFICITY: Expressed in endocrine cells of the larval midgut CC (at protein level) (PubMed:24098432, PubMed:24850274). Also expressed CC in endocrine cells of the midgut of adult males and females (at protein CC level) (PubMed:24098432). In the midgut, expression occurs mainly in CC the anterior region (at protein level) (PubMed:24098432). In the larval CC central nervous system, expressed in about 40 neurons in the brain CC hemispheres and ventral nerve cord (at protein level) CC (PubMed:24098432). Highly expressed in larval and adult gut with low CC levels in larval and adult brain (PubMed:24098432). Very little CC expression in the larval fat body (PubMed:26168160). However, another CC study shows high levels of expression in the larval fat body as well as CC the larval gut with low levels in the larval central nervous system CC (PubMed:26020940). {ECO:0000269|PubMed:24098432, CC ECO:0000269|PubMed:24850274, ECO:0000269|PubMed:26020940, CC ECO:0000269|PubMed:26168160}. CC -!- DEVELOPMENTAL STAGE: Very low expression in eggs. Expression increases CC during the first instar larval stage, decreases gradually during the CC second and third instar larval stages and in pupae and increases in CC adults. {ECO:0000269|PubMed:24098432}. CC -!- INDUCTION: Repressed in larvae by starvation for 18 hours with levels CC recovering when larvae are refed with yeast or glucose. CC {ECO:0000269|PubMed:26020940}. CC -!- MASS SPECTROMETRY: Mass=1347.69; Method=MALDI; CC Evidence={ECO:0000269|PubMed:23293632}; CC -!- MASS SPECTROMETRY: Mass=1348.53; Method=MALDI; CC Evidence={ECO:0000269|PubMed:21214272}; CC -!- DISRUPTION PHENOTYPE: Reduced food intake in adults and larvae, reduced CC locomotor activity, delayed development with mutants taking 200 hours CC to develop from egg to pupa compared to 130 hours for wild-type flies, CC reduced levels of the insulin-like peptides Ilp2 and Ilp3, and reduced CC wing size (PubMed:26168160). Reduced levels of insulin-like peptide CC Ilp5 and reduced body weight of mid-third instar larvae CC (PubMed:26020940). {ECO:0000269|PubMed:26020940, CC ECO:0000269|PubMed:26168160}.
