Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: octopamine receptor activity.
There is experimental evidence that it is involved in the biological process: ovulation; cellular calcium ion homeostasis; elevation of cytosolic calcium ion concentration involved in G-protein signaling coupled to IP3 second messenger.
24 alleles are reported.
The phenotype of these alleles is annotated with: ovariole.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: GPCR, rhodopsin-like superfamily; GPCR, rhodopsin-like, 7TM.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of extremely low expression.
Peak expression observed within 12-24 hour embryonic stages, during early larval stages, during late pupal stages, in stages of adults of both sexes.
