Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: guanyl-nucleotide exchange factor activity.
There is experimental evidence that it is involved in the biological process: myoblast fusion; central nervous system development; inter-male aggressive behavior; actin cytoskeleton organization.
52 alleles are reported.
The phenotypes of these alleles are annotated with: commissure; ventral nerve cord commissure; midline glial cell; embryonic myoblast.
It has 4 annotated transcripts and 4 annotated polypeptides.
Protein features are: IQ motif, EF-hand binding site; Pleckstrin homology domain; Pleckstrin homology-type; SEC7-like; SEC7-like, alpha orthogonal bundle.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression.
Peak expression observed within 00-12 hour embryonic stages.
