Gene Summary
pale (ple) encodes a cytosolic tyrosine hydroxylase that catalyzes the hydroxylation of L-tyrosine to form L-dopa, the first and rate-limiting step in the synthesis of dopamine (and eventually, melanin). Dopamine acts as a neurotransmitter regulating various processes. It is also a precursor for the synthesis of melanin and the cuticle sclerotization precursors, N-acetyldopamine (NADA) and N-β-alanyldopamine (NBAD).

Gene Group (FlyBase)
MONOOXYGENASES, REDUCED PTERIDINE AS ONE DONOR -
Monooxygenases, reduced pteridine as one donor include, dehydrogenases that catalyze an oxidation-reduction reaction in which hydrogen or electrons are transferred from reduced pteridine and one other donor, and one atom of oxygen is incorporated into one donor.
Pathway (FlyBase)
DOPAMINE BIOSYNTHESIS -
Dopamine is a monoamine synthesised in the cytosol from L-tyrosine. Dopamine produced by dopaminergic neurons acts as a neurotransmitter which binds G protein-coupled receptors regulating various processes including locomotor activity, sensory processing, courtship and egg-laying. Dopamine produced by epidermal cells is used for: (i) the synthesis of melanin which is involved in immunity and cuticle pigmentation; and (ii) the production of the cuticle sclerotization precursors, N-acetyldopamine (NADA) and N-β-alanyldopamine (NBAD). (Adapted from FBrf0255924 and FBrf0224779.)
Protein Function (UniProtKB)
Plays an important role in the physiology of adrenergic neurons.
(UniProt, P18459)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
ple: pale
Homozygous lethal in embryo. Mutant embryos have unpigmented cuticle and head skeleton. Catecholamine levels reduced or absent (Budnick and White, 1987).
Summary (Interactive Fly)

tyrosine hydroxylase - catalyzes the first and rate-limiting step in catecholamine biosynthesis - mediates the oxidation of tyrosine to L-DOPA - DOPA decarboxylase may then metabolize L-DOPA to dopamine

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Additional Descriptive Data

Expression assayed at stages 9, 11, 13, and 17. Expression may be continuous between assayed stages in some tissues.

ple-RB transcript isoform is expressed is ventral segmentally repeated rows of the epidermal cells that produce the denticle belts.

The 3.7 kb ple transcript is restricted to neural tissue. It is detected in adult head or brain tissue and from larval central nervous system using RT-PCR.

The 3.2 kb ple transcript, the shorter of the two type II ple isoforms, is epidermal, and is detected in larvae and adults using RT-PCR. Adult head, thorax, abdomen and larval epidermis express the short form of ple. A low level of expression is also seen in central nervous system tissue from larvae and adults. The 3.2 kb transcript is also detected in adult heads using Northern hybridization.

ple transcripts are detected in adult heads and in first instar larvae.

Additional Descriptive Data

ple is expressed in approximately 10 PPL1, 8 PPL2, 6 PPM1/2, 5 PPM3 and 4 PAL dopaminergic neurons.

ple protein is expressed in the dopaminergic clusters PAL (5 neurons), PAM (74 neurons), PPL1 (12 neurons), PPL2ab (6 neurons), PPM1 (1 neuron), PPM2 (10 neurons) and PPM3 (8 neurons). ple protein labels more neurons in the PAM cluster than ScerGAL4ple.PF or ScerGAL4Ddc.HL9.

Expression of ple is widely expressed throughout the mushroom body horizontal lobe, but is particularly intense at their distal tips.

ple-PA protein isoform is CNS-specific.

        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.

        Larvae treated with tyrosine hydroxylase inhibitors exhibit severely reduced dopamine levels. Larvae are negatively phototactic, demonstrate a strong aversion to salt, are strongly attracted to heptanol and locomotor and feeding abilities are normal. However larvae do become akinetic and eventually die. Some do survive to pupariation and adults that eclose exhibit normal cuticle formation and cuticle. Reduced levels of dopamine affect adult fertility, ovarian development is affected.

        A segment of ple from -1kb to +7kb shows limited rescue of ple mutants, FBrf0058913. The addition of 3.5kb 5' flanking ple DNA allows rescue to pupation depending on the site of integration but very limited rescue to adulthood.

        ple is encoded via alternatively spliced exons to generate the major (Type II) and minor (Type I) isoforms. Alternative RNA processing generates 3 types of RNA that differ in the length of the 3' untranslated region, IL, IIS and IIL. IL is specifically expressed in the CNS and IIS is the hypoderm.

        ple encodes the structural gene for tyrosine hydroxylase.

        ple gene product catalyses the first and rate-limiting step in the synthesis of catecholamines. An 8kb genomic fragment contains the necessary temporal and spatial elements for correct expression.

        ple mutants display unpigmented cuticle and head skeleton.
