Automatically generated summary

See sections below for more information
The gene comatose is referred to in FlyBase by the symbol Dmel\comt (CG1618, FBgn0000346). It is a protein_coding_gene from Drosophila melanogaster. It is reported to have molecular function: ATPase activity. There is experimental evidence that it is involved in the biological process: Golgi organization; regulation of short-term neuronal synaptic plasticity; phagocytosis, engulfment. 38 alleles are reported. The phenotypes of these alleles are annotated with: Golgi stack; retina; Golgi apparatus; central nervous system; NMJ bouton; synapse; embryonic/larval heart. It has one annotated transcript and one annotated polypeptide. Protein features are: ATPase, AAA+ type, core; ATPase, AAA-type, VAT, N-terminal; ATPase, AAA-type, conserved site; ATPase, AAA-type, core; Aspartate decarboxylase-like fold; Cell division protein 48, Cdc48, domain 2. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression. Peak expression observed within 18-24 hour embryonic stages, during early larval stages, during late pupal stages, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system. Expression at moderate levels in the following post-embryonic organs or tissues: adult ovary, adult testis. Comments on Affy2 ProbeSet: ProbeSet 1639825_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of comt. Gene sequence location is X:13153030..13156521.

hide Phenotypic Description from the Red Book (Lindsley & Zimm 1992)
Gene/Allele symbols may differ from current usage
comt: comatose (J.C. Hall)
Larvae or adults become paralyzed when exposed to high temperatures, but this requires many seconds for induction; recovery from immobility on lowering of temperature is slow and directly correlated with duration of paralysis; most of the comt alleles do not induce relatively rapid paralysis until 38 (Siddiqi and Benzer, 1976), but two (com101, com102) cause pass-out at 29 (Homyk, Szidonya, and Suzuki, 1980, Mol. Gen. Genet. 177: 553-65); the mutations induce graded decrease and recovery of function of synapses at neuromuscular junctions as temperature is raised and lowered (Siddiqi and Benzer, 1976); several alleles are cold sensitive for paralysis as well as heat sensitive (Siddiqi and Benzer, 1976). ERG normal (Homyk and Pye, 1989, J. Neurogenet. 5: 37-48).

S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.
comt and Nsf2 exhibit similar functional properties but have evolved distinct tissue-specific roles. comt is required in the nervous system beginning at the adult stage of development whereas Nsf2 is required in the mesoderm beginning at the first larval instar. The comt and Nsf2 proteins can functionally substitute for one another.
comt normally dissociates and recycles SNARE proteins during the interval between exocytosis and endocytosis in the synaptic vesicle cycle.
Paralysis in comt mutant flies is activity dependent.
Evidence of multiple, highly related isoforms of NSF in a single species suggests that in some tissue membranes fusion and/or secretion has a specific role during development.
Mutations of comt are defective in one component of the molecular machinery mediating vesicle targetting and fusion, N-ethylmaleimide-sensitive fusion protein (NSF). comt exhibits an apparent defect in synaptic transmission which is the first functional evidence that NSF in involved in this process.
Drosophila has a second N-ethylmaleimide-sensitive fusion protein (NSF) homolog, Nsf2. comt and Nsf2 display overlapping but different temporal expression patterns.
comt gene has been cloned and the gene product characterised.
The neurosecretory apparatus of the presynaptic nerve terminal contains a core complex of conserved secretory proteins, comt is a component this complex.
Larvae or adults become paralyzed when exposed to high temperatures, but this requires many seconds for induction; recovery from immobility on lowering of temperature is slow and directly correlated with duration of paralysis; most of the comt alleles do not induce relatively rapid paralysis until 38oC (Siddiqi and Benzer, 1976), but two (comt2, comt3) cause pass-out at 29oC (Homyk, Szidonya and Suzuki, 1980); the mutations induce graded decrease and recovery of function of synapses at neuromuscular junctions as temperature is raised and lowered (Siddiqi and Benzer, 1976); several alleles are cold-sensitive for paralysis as well as temperature-sensitive (Siddiqi and Benzer, 1976). ERG normal (Homyk and Pye, 1989).
