Automatically generated summary

See sections below for more information
The gene egalitarian is referred to in FlyBase by the symbol Dmel\egl (CG4051, FBgn0000562). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: mRNA binding. There is experimental evidence that it is involved in the biological process: germarium-derived oocyte fate determination; intracellular mRNA localization; oogenesis; mRNA transport. 26 alleles are reported. The phenotypes of these alleles are annotated with: organ system; multicellular structure; female germline cyst; anatomical structure; organelle; cytoplasmic part; somatic cell; portion of tissue; egg; somatic stem cell; germarium; vitellarium; nuclear part; nervous system; protein complex; synapse; karyosome. It has one annotated transcript and one annotated polypeptide. Protein features are: 3'-5' exonuclease; Ribonuclease H-like. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression. Peak expression observed within 00-06 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Many larval and adult organs/tissues expressed at moderate levels. Expression at high levels in the following post-embryonic organs or tissues: adult crop, larval/adult salivary gland. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, adult central nervous system, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult fat body, larval trachea, adult female reproductive system, adult male accessory gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1641303_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of egl. Gene sequence location is 2R:19622427..19634348.

hide Phenotypic Description from the Red Book (Lindsley & Zimm 1992)
Gene/Allele symbols may differ from current usage
egl: egalitarian (T. Schupbach)
Female sterile. Defect in cell fate detectable in anterior germarium. In contrast to wild-type, in all egl alleles all sixteen cells per cyst enter pachytene; subsequently all sixteen revert to nurse-cell morphology and behavior (Carpenter). Egg chambers increase in volume along the ovariole, but do not take up yolk. No chorion is formed. BicD/+ females simultaneously heterozygous for egl1 or egl2 fail to form double-abdomen embryos (Mohler and Wieschaus, 1986, Genetics 112: 803-22).

Additional Descriptive Data
egl RNA is enriched in single cells when the 16-cell cyst forms in region 2A of the germarium. Between stages S2 and S7, egl RNA is concentrated at the posterior cortex of the oocyte. As the oocyte starts to accumulate yolk, egl transcripts localize to an anterior ring at the nurse cell-oocyte boundary. By stage S10, they are distributed evenly throughout the oocyte and persist in the oocyte until early embryogenesis.

Additional Descriptive Data
The BicD and egl proteins, as previously described for the orb protein, accumulate in the presumptive oocyte following fusome disassembly in germarium region 2a during oocyte specification and are relocalized to the posterior of the oocyte between germarium regions 2b and 3 during oocyte polarization.
egl protein is first detected in the germarium and is evenly distributed in the newly formed 16-cell cyst. By stage S1 of oogenesis, it localizes to a single cell, the future oocyte. From stages S2 to S7 egl protein is enriched at the posterior cortex of the oocyte, wherever the oocyte abuts the follicle cells. At stage S8, it shifts to the anterior cortex in a ring around the margin of the oocyte where the oocyte, nurse cells, and follicle cells meet. Staining is particularly pronounced around the oocyte nucleus. No protein is detec ed in the oocyte after stage S10. egl protein distribution in oocytes closely resembles the distribution of the minus end of microtubules. It was shown that disrupting microtubule organization abolishes egl protein localization. In addition, egl protein and BcD protein were found to have identical distributions during all stages of oogenesis. Localization of egl protein depends on BicD protein and vice versa.

Despite lacking a canonical RNA-binding motif, egl protein directly recognises active mRNA localisation elements.
egl promotes the initiation of rapid minus-end directed movement of mRNAs along microtubules.
egl mediates the apical localisation of insc mRNA in embryonic neuroblasts.
ctp interacts with egl through a ctp interaction domain near the C terminus of egl and a well established binding motif in ctp.
par-1 appears to act on the cytoskeleton to affect polarisation within the oocyte in conjunction with BicD, egl and dynein.
All of the cells in the female germline cyst form synaptonemal complex in egl mutants.
BicD exists as a multimeric protein complex consisting of egl and at least two BicD monomers.
egl protein colocalises with BicD protein to the oocyte in three stages that correlate with the stepwise polarization of the oocyte. Immunoprecipitation experiments show that both proteins are part of a protein complex. Results propose that the egl-BicD protein complex links microtubule polarity and RNA transport.
Oocyte determination requires egl function in the germ line, but not in the surrounding follicle cells. During early oogenesis the egl-BicD protein complex is required to transport factors promoting oocyte differentiation; during later stages the complex directs the sorting of RNA molecules required for anterior-posterior and dorsoventral patterning of the embryo.
The egl locus is responsible for two functions in cell fate choice in oogenesis: early on it is necessary for inhibition of meiotic entry in the "obligate" pro-nurse cells; later it is necessary for meiotic maintenance in the "winning" pro-oocyte. Both roles can be attributed to a single function by invoking gradients through the early cyst; the egl+ function appears to be required for the normal function of these gradients.
egl mutants have disrupted microtubule cytoskeletons and fail to differentiate an oocyte.
Recessive mutations at egl and BicD, and microtubule assembly inhibitors, disrupt the formation and maintenance of the single polarized microtubule cytoskeleton that connects the oocyte to the 15 nurse cells at the time the oocyte is determined.
Alleles of egl and BicD were used to show that the differentiation of an oocyte is required for maintainance but not establishment of follicle polarity.
In egl mutant ovaries the cell which would normally develop as an oocyte instead forms a 16th nurse cell. egl acts as a dominant suppressor of BicD.
egl is required for oogenesis and the determination of polarity within the embryo.
The egl locus affects early oogenesis: mutations cause the production of few, defective germ cells.
