Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: dimethylallyltranstransferase activity; geranyltranstransferase activity; farnesyltranstransferase activity.
There is experimental evidence that it is involved in the biological process: germ cell migration; embryonic heart tube development; neurogenesis.
21 alleles are reported.
The phenotypes of these alleles are annotated with 11 unique terms, many of which group under: multicellular structure; organ system subdivision; adult segment; organ system; anatomical structure; adult; sense organ; extended germ band embryo; eo support cell; embryonic pericardial cell; cephalopharyngeal skeleton.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Polyprenyl synthetase; Polyprenyl synthetase-related; Terpenoid synthase.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of moderate expression.
Peak expression observed at stages throughout embryogenesis, during late larval stages, during early pupal stages, in adult female stages.
