Expressed in antennal basiconic sensillum ab1-3 and 7 and in sensillum trichodeum. Observed in tormogen cells. Probably also present in trichogen cells but wasn't directly demonstrated.
Transcripts are detected in RNA from antennae but not in RNA from chemosensory depleted heads or bodies. In situ hybridization reveals that expression is limited to the ventro-lateral region of the third antennal segment, in a pattern consistent with the distribution of sensilla trichodea. In deeper sections, expression is observed beneath sensilla trichodea sensory hairs.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Source for identity of: Obp83a Pbprp3
Identified as a gene with significant level of mRNA cycling as assessed by expression analysis using high density oligonucleotide arrays with probe generated from adult heads harvested over six time points over the course of a day. Shows alteration in expression in a Clk mutant background.
Os-E and Pbprp3 are located about 1kb apart and contain a similar exon-intron organisation. Expression of both proteins is restricted spatially to two distinct types of olfactory hairs located in the ventrolateral region of the antenna. Immunocytochemical EM studies reveal that all sensilla examined express both proteins, thus, an individual sensilla can contain more than one odorant-binding protein.
Isolated from a subtracted antennal cDNA library enriched for cDNAs expressed in the antennae but not the rest of the head or body of adult flies.
Pbprp3 is one of seven clones that have been identified from subtracted cDNA libraries, containing antennal cDNA from which head cDNAs have been subtracted. Pbprp1 protein has sequences similar to those of Moth Pheromone-binding proteins (PBPs). Members of the PBP-related family are expressed in different subsets of sensilla.
