Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: GDP-dissociation inhibitor activity.
It is reported to be involved in the biological process: neurotransmitter secretion; vesicle-mediated transport.
22 alleles are reported.
The phenotypes of these alleles are annotated with: trichogen cell; puparium; pole cell; embryonic epidermis; mesothoracic tergum; melanotic mass.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: GDP dissociation inhibitor; Rab GDI protein.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed within 00-18 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in adult female stages.
