The gene Insulin-like peptide 2 is referred to in FlyBase by the symbol Dmel\Ilp2 (CG8167, FBgn0036046). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: insulin receptor binding. There is experimental evidence for 12 unique biological process terms, many of which group under: biological regulation; regulation of growth; regulation of multicellular organismal process; positive regulation of biological process; homeostatic process; cellular component organization or biogenesis; larval feeding behavior; determination of adult lifespan; carbohydrate utilization; multi-organism reproductive process. 11 alleles are reported. The phenotype of these alleles is annotated with: wing. It has one annotated transcript and one annotated polypeptide. Protein features are: Insulin family; Insulin, conserved site; Insulin-like. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of no expression detected. Peak expression observed during early larval stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult head, larval/adult central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1629220_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Ilp2. Gene sequence location is 3L:9792798..9793540.

Transcript is detected in the embryo with low levels in the embryonic mesoderm and high signal in the midgut. During the third larval instar transcript is ubiquitously expressed in imaginal discs at a low level and a high signal is detected in seven cells in each brain hemisphere in an anterior-medial postion
Ilp2 is expressed in a bilaterally symmetrical cluster of 5 to 7 neurosecretory cells in the pars intercerebralis. It is co-expressed with Ilp3 and Ilp5.
Transcript is expressed in two clusters of cells in the pars intercerebralis corresponding to the medial neurosecretory cell clusters (m-NSCs) from the first through third larval instars.
Ilp2 protein is expressed in the insulin producing cells (IPC), a subset of the dorsomedial neurosecretory cells of the pars intercerebralis and in other dorsal cells of this cluster. The IPC cells that express Ilp2 are also labeled by the expression of Scer\GAL4GABA-B-R2.PR.
Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult head, larval/adult central nervous system.
