General annotation (Comments)
| Function | 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 the centrosomes of the mitotic spindle. Required at the final stage of oogenesis for meiosis I metaphase arrest and for progression beyond this stage. Ref.3 Ref.4 Ref.5 Ref.6 |
| Catalytic activity | ATP + RNA(n) = diphosphate + RNA(n+1). Ref.5 |
| Cofactor | Magnesium or manganese By similarity. |
| Subunit structure | Interacts with orb, an RNA-binding protein, generating an ovarian cytoplasmic polyadenylation complex. Ref.5 |
| Subcellular location | |
| Tissue specificity | Expressed in ovaries. Not expressed in adult males. Ref.5 |
| Developmental stage | |
| Disruption phenotype | Pronuclear migration does not occur in activated eggs. Defects in spindle structures (abnormally shaped spindles, spindle spurs, ectopic spindles associated with lost chromosomes and mispositioning of the meiosis II spindles) correlated with very high frequencies of chromosome non-disjunction and loss. The polar body nuclei do not associate with their normal monastral arrays of microtubules, the sperm aster is reduced in size, and the centrosomes often dissociate from a mitotic spindle that forms in association with the male pronucleus. Ref.3 Ref.4 Ref.6 |
| Sequence similarities | Belongs to the DNA polymerase type-B-like family. GLD2 subfamily. Contains 1 PAP-associated domain. |
