The gene Inositol 1,4,5,-tris-phosphate receptor is referred to in FlyBase by the symbol Dmel\Itp-r83A (CG1063, FBgn0010051). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: inositol 1,4,5-trisphosphate-sensitive calcium-release channel activity. There is experimental evidence that it is involved in the biological process: larval feeding behavior; cellular calcium ion homeostasis; stabilization of membrane potential; response to oxidative stress; nuclear division; flight behavior; molting cycle, chitin-based cuticle; mushroom body development; release of sequestered calcium ion into cytosol; sensory perception of taste. 42 alleles are reported. The phenotypes of these alleles are annotated with: dorsal medial muscle; mushroom body; wing margin; mesothoracic tergum; wing; antennal lobe; indirect flight muscle. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Inositol 1,4,5-trisphosphate-binding protein receptor; Inositol 1,4,5-trisphosphate/ryanodine receptor; Intracellular calcium-release channel; Ion transport domain; MIR motif; RyR/IP3R Homology associated domain; Ryanodine receptor-related. 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 12-18 embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: adult brain, adult crop, adult fat body, adult salivary gland. Comments on Affy2 ProbeSet: ProbeSet 1639461_a_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of Itp-r83A. Gene sequence location is 3R:1342839..1365006.

Itp-r83A transcripts are expressed throughout development. Highest levels in adults are in fractions containing appendages (legs, antennae, wings, seta). Strong expression in the retina, antenna, legs and thorax was deduced.
Itp-r83A protein is detected in the second and third antennal segments as well as in the proboscis and the maxillary palps. In these locations, it is loclaized to the base of sensory hairs used for taste or olfaction. In the brain, it is restricted to cell bodies and is probably perinuclear. Itp-r83A protein is observed associated with nuclei of each photoreceptor, cone and pigment cell. It is also present in the muscles of the head. In embryos, Itp-r83A protein is observed in mesoderm. Protein is first observed at stage 9 and reaches a maximum in stage 13. It is present in somatic and visceral mesoderm and in two rows of cardioblasts along the dorsal midline. Staining begins to fade by stage 14. In the cephalic region, protein is observed in the procephalic mesoderm starting at stage 9 and is present in pharyngeal muscle by stage 13. In third instar larvae, Itp-r83A protein is found in myoblasts in the wing and leg discs. In the eye disc, staining is associated with photoreceptor cells just behind the morphogenetic furrow. In pupae, Itp-r83A protein was examined in the development of the DLMs. It is expressed in the myoblasts in the region of the DLMs and later in the fused myoblasts, and later still in the developing muscle fibres. Itp-r83A protein is found to be expressed also in antennal muscles during their development.
Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: adult brain, adult crop, adult fat body, adult salivary gland.

Both Itp-r83A and rut signalling pathways are involved in regulating larval molting. Regulation of 20-hydroxyecdysone peaks during larval molting may operate through a feedback loop requiring Pka-C1 and the Itp-r83A receptor.
Expression pattern analysis suggests that the IP3 signalling pathway is used during muscle development, primarily when myoblasts undergo rapid multiplication, in both embryos and pupae. In adults IP3 is probably a second messenger in more than one sensory transduction pathway.
