The gene moira is referred to in FlyBase by the symbol Dmel\mor (CG18740, FBgn0002783). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding. There is experimental evidence that it is involved in the biological process: imaginal disc-derived wing margin morphogenesis; negative regulation of S phase of mitotic cell cycle; imaginal disc-derived wing vein morphogenesis; imaginal disc-derived wing vein specification; positive regulation of transcription, DNA-dependent; imaginal disc-derived leg morphogenesis; neurogenesis. 28 alleles are reported. The phenotypes of these alleles are annotated with: midgut constriction 2; ventral nerve cord commissure; eye; embryonic head; macrochaeta; presumptive embryonic/larval peripheral nervous system; midgut constriction 1; wing. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: BRCT domain; Homeodomain-like; SANT domain; SANT/Myb domain; SWIRM domain; Winged helix-turn-helix transcription repressor DNA-binding domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderate expression. Peak expression observed within 00-12 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Nearly all larval and adult tissues/organs expressed at moderate levels. Expression at high levels in the following post-embryonic organs or tissues: larval central nervous system, adult ovary. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult spermathecae, adult male accessory gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1640418_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of mor. Gene sequence location is 3R:11793856..11798636.

mor: moira (J.A. Kennison)
Isolated as a dominant suppressor of the antenna-to-leg transformation in a Pc2 AntpNs double heterozygote.
Strongly suppresses the antennal transformation in an AntpNs
heterozygote, but does not suppress the antennal transformation in a strain containing a heat-shock driven Antennapedia
cDNA. Also behaves as a dominant suppressor of Pc and Pcl
mutations. All alleles associated with a common recessive
embryonic lethality. Mitotic clones induced during larval
growth lead to transformation of haltere tissue to wing tissue. Ubx130/mor has low frequency of haltere to wing
transformation.

mor transcripts are detected by northern blot at 0-4hr of embryogenesis, reach a peak in 4-8hr embryos and decline until the 2nd instar larval stage. The are expressed also in third instar larvae, pupae, and adult males and females. mor transcripts are ubiquitously expressed in early embryos as assayed by in situ hybridization. They are enriched in the CNS, midgut and hindgut of older embryos.

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.
Pc, Scm, Psc, ph-p and ph-d contribute to the PRC1 (Polycomb repressive complex 1). PRC1 directly antagonizes ATP-dependent remodeling of nucleosomal arrays in a purified system and may directly modulate (and be modified by) SWI/SNF (brm/mor) activity.
mor is an essential gene necessary for the transcriptional regulation of multiple homeotic and segmentation genes. Germline clonal analysis demonstrates that mor is important for proper oogenesis and somatic clonal analysis demonstrates that mor is required for the correct differentiation of imaginal structures in the adult cuticle.
Isolated as a dominant suppressor of the antenna-to-leg transformation in a Pc2AntpNs double heterozygote. Strongly suppresses the antennal transformation in an AntpNs heterozygote, but does not suppress the antennal transformation in a strain containing a heat-shock driven Antp cDNA. Also behaves as a dominant suppressor of Pc and Pcl mutations. All alleles associated with a common recessive embryonic lethality. Mitotic clones induced during larval growth lead to transformation of haltere tissue to wing tissue. Ubx130/mor has low frequency of haltere to wing transformation.
mor is one of the 18 loci identified in a screen for dominant modifiers of Pc and/or Antp phenotypes. Alleles of Pc, Pcl, Scm, Dll, brm, kto, Scr and trx show clear dominant enhancement or suppression of AntpScx, whereas alleles of vtd, Vha55, Su(Pc)37D, urd, mor, skd and osa do not. Mosaic analysis with mutant alleles reveals homeotic transformations in adult cuticle.
