The gene Hexokinase C is referred to in FlyBase by the symbol Dmel\Hex-C (CG8094, FBgn0001187). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: hexokinase activity. There is experimental evidence that it is involved in the biological process: lateral inhibition. 10 alleles are reported. The phenotypes of these alleles are annotated with: chaeta; tormogen cell. It has one annotated transcript and one annotated polypeptide. Protein features are: Hexokinase; Hexokinase, C-terminal; Hexokinase, N-terminal. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of extremely low expression. Peak expression observed 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 Malpighian tubules, adult heart, adult fat body, adult spermathecae, adult carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult eye, adult hindgut. Comments on Affy2 ProbeSet: ProbeSet 1630147_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Hex-C. Gene sequence location is 2R:11106342..11107834.

Hex-C
The structural gene for hexokinase-C [HEX-C (EC
2.7.1.1)]. The enzyme is a monomer of estimated molecular
weight 42,000 _ 3,000 (Moser et al.) or 35,000 (Leigh Brown in
Racine, Langley, and Voelker, 1980, Environ. Mutagen.
2: 167-77). Activity present in all developmental stages
except freshly laid eggs; restricted to fat body in larvae,
but present in many organs in adult. Weakly active or inactive in cell line (Deber, 1974, Wilhelm Roux's Arch. Entwicklungsmech. Org. 174: 1-9). HEX-C activity not necessary for
survival; null mutants viable (Burkhart, Montgomery, Langley
and Voelker, 1984, Genetics 107: 295-306). Purification and
biochemical characterization of enzyme described by Moser et
al..

The effects of a high sucrose diet on live weight, total protein, stored lipid and glycogen and crude activities of 12 enzymes involved in energy metabolism are quantified. The activities of many enzymes are reduced by the sucrose treatment.
The isoacceptor pattern of tRNA:E4 is altered in l(2)me1 mutant flies, supporting the hypothesis that the l(2)me1 mutation may be a deletion of part of the tRNA:E4 cistrons (and Hex-C) located at 2-72.
No linkage disequilibrium has been detected between Gpdh, Mdh1, Adh, Hex-C, Est-C or Fdh. Significant linkage disequilibrium has been detected between In(2L)NS and Hex-C.
The structural gene for hexokinase-C (HEX-C). The enzyme is a monomer of estimated molecular weight 42,000 +/- 3,000 (Moser et al.) or 35,000 (Leigh Brown in Racine, Langley and Voelker, 1980). Activity present in all developmental stages except freshly laid eggs; restricted to fat body in larvae, but present in many organs in adult. Weakly active or inactive in cell line (Debec, 1974). HEX-C activity not necessary for survival; null mutants viable (Burkhart et al., 1984). Purification and biochemical characterization of enzyme described by Moser et al., 1980.
