LD29322p; Heparin binding; low-density lipoprotein particle receptor binding; receptor antagonist activity. It is involved in the biological process described with: regulation of receptor-mediated endocytosis.

LD24340p.

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.

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.

Mitosis initiation protein fs(1)Ya; Female sterile (1) Young arrest (fs(1)Ya) encodes a maternally-expressed protein that is required for mitotic phase initiation during early embryogenesis. It localizes in the nuclear lamina of the embryo, and binds DNA and the product of His2B. In developing oocytes the product of fs(1)Ya is cytoplasmic, but enters nuclei when it is dephosphorylated during egg activation.

Maternal effect protein oskar; Organizes the germ plasm and directs localization of the posterior determinant nanos. Oskar protein is required to keep nos RNA and staufen protein at the posterior pole.

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.

Poly(A) RNA polymerase gld-2 homolog B; Cytoplasmic poly(A) RNA polymerase that adds successive AMP monomers to the 3'-end of specific maternal RNAs (bcd, Tl, and tor), forming a poly(A) tail, during late oogenesis and early embryogenesis. In contrast to the canonical nuclear poly(A) RNA polymerase, it only adds poly(A) to selected cytoplasmic mRNAs. Required for localization of mRNAs to both poles of the egg, to recruit or maintain known centrosomal proteins with two types of microtubule organizing centers (MTOCs): the central MTOC that forms between the meiosis II tandem spindles and [...]

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.
