Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: GTPase activity; GTP binding.
An electronic pipeline based on InterPro domains suggests that it is involved in the biological process: protein transport; small GTPase mediated signal transduction.
5 alleles are reported.
No phenotypic data is available.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Small GTP-binding protein domain; Small GTPase superfamily; Small GTPase superfamily, Rab type.
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 00-06 hour embryonic stages, in adult female stages.
