The gene Dipeptidase B is referred to in FlyBase by the symbol Dmel\Dip-B (CG9285, FBgn0000454). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: tripeptidyl-peptidase activity; dipeptidyl-peptidase activity. There is experimental evidence that it is involved in the biological process: proteolysis. 7 alleles are reported. No phenotypic data is available. It has 3 annotated transcripts and 3 annotated polypeptides. Protein features are: Leucine aminopeptidase/peptidase B; Peptidase M17, leucyl aminopeptidase, C-terminal. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of low expression. Peak expression observed within 00-06 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in adult female stages. Summary of FlyAtlas Anatomical Expression Data: High or moderate levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult central nervous system, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval fat body, larval/adult salivary gland, larval trachea, adult female reproductive system, adult testis, larval carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval central nervous system, adult crop, adult fat body, adult male accessory gland, adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1635449_s_at completely aligns to an exonic region common to each of the 3 FlyBase-annotated transcript isoforms of Dip-B. Gene sequence location is 3R:9608012..9611401.

Dip-B: Dipeptidase B
Structural gene for dipeptidase B [DIP-B(EC
3.4.14.?.)], which is virtually monomorphic in natural populations but which differs in electrophoretic mobility from
dipeptidase-B variants in D. simulans. Substrate specificities determined by Laurie-Ahlberg (1982, Biochem. Genet.
20: 407-24).

Dip-B is present atfairly uniform specific activities throughout development. Specificactivity is highest in pupae and lowest in feeding stages. Dip-Bspecific activity was also found to be fairly uniform in all tissuesstudied except in gut and Malphigian tubules where it is higher thanaverage and adult thorax where it is low.

Shows particularly robust cycling of transcription in adult heads, as assessed by expression analysis using high density oligonucleotide arrays with probe generated during three 12-point time course experiments over the course of 6 days. Shows significant change of expression pattern in circadian mutant background; decreased expression in per01, tim01 and increased expression in ClkJrk background.
Larvae of genetically different lines were reared under varying levels of osmotic stress to study the genetic basis of the correlation of peptidase activities in response to environmental challenge.
Examination of D.melanogaster lines revealed genetic variation of Dip-A and Dip-B within sets of lines that only differed in the second or third chromosome. Experiments were undertaken to identify the types of activity modifiers that may be polymorphic in natural populations and to characterize the genetic organization of the modifiers.
Structural gene for dipeptidase B (DIP-B), which is virtually monomorphic in natural populations but which differs in electrophoretic mobility from dipeptidase-B variants in D.simulans. Substrate specificities determined (Laurie-Ahlberg, 1982).
