Putative vitellogenin receptor; Involved in uptake of vitellogenin by endocytosis.

Tubulin alpha-4 chain; alpha-Tubulin at 67C (alphaTub67C) encodes a protein that form heterodimers with beta-tubulins to polymerise and form microtubules. Tubulin molecules containing the product of alphaTub67C are essential for fast growth of the microtubules during the initial cleavage divisions of embryogenesis.

Bag of marbles (bam) encodes a protein involved in gametogenesis that is associated with the fusome, a germ cell-specific organelle. It contributes to the fate determination of germline stem cells, in which bam is negatively regulated by the BMP signaling pathway.

Poly(U)-binding-splicing factor half pint; Splicing factor that regulates oogenesis and controls both mitosis and mRNA localization in the germline by regulating mRNA splicing of a subset of genes within the ovary. Probably acts by regulating the alternative splice site selection of the otu transcript. Also regulates the alternative splicing of eIF4E1 and grk, while it is not involved in the splicing of par-1, sqd and psq. Belongs to the RRM half pint family.

Thioredoxin-1; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. As a reducing substrate of peroxiredoxin 1, thioredoxin 2 is preferred over thioredoxin 1. Required for female meiosis and early embryonic development.

Chorion peroxidase; Peroxinectin-like (Pxt) encodes a cycloxygenase-like enzyme that contributes to the synthesis of prostaglandins. Prostaglandins activate G protein-coupled receptor signaling. Its roles include oogenesis, sperm individualization, morphogenesis, nucleolar structure, temporal control of gene expression, and regulation of gene amplification; Belongs to the peroxidase family. XPO subfamily.

Female sterile (1) M3 (fs(1)M3) encodes a protein that is required, along with the products of fs(1)N and clos, for their accumulation at the vitelline membrane and function in vitelline membrane integrity and Torso receptor activation.

CG5272 protein; Giant nuclei (gnu) encodes a regulatory subunit of the PNG kinase complex, which regulates the levels of the protein encoded by CycB. Members of this complex are required maternally for the normal nuclear divisions of the syncytial embryo.

Protein matrimony; Polo kinase inhibitor required to maintain G2 arrest in the meiotic cell cycle in females. Holds heterochromatically paired homologs together from the end of pachytene until metaphase I. Haploinsufficient locus for homologous achiasmate segregation and may be required for the maintenance of heterochromatic pairings.
