Gene Snapshot
wispy (wisp) encodes a conserved cytoplasmic poly-A polymerase of the GLD2 family that is expressed in the female germline and, at low levels, in the nervous system. Its maternal germline expression is essential for completion of normal meiosis by oocytes at egg activation. The product of wisp elongates the poly-A tails of many mRNAs during egg activation. This activity is essential for the translation of maternal mRNAs. [Date last reviewed: 2019-03-21]

POLY(A) POLYMERASES -
Poly(A) polymerases (PAPs) catalyze the addition of nontemplated adenylyl residues to the 3' ends of RNA substrates. In eukaryotes, canonical PAPs polyadenylate mRNAs prior to export from the nucleus to the cytoplasm, which is required for the stabilization, export and efficient translation of transcripts. In contrast, non-canonical PAPs add poly(A) tails to a different types of RNAs to stimulate their degradation - similar to the function of bacterial poly(A) tails. PAPs therefore play crucial and diverse roles in the regulation of gene expression. (Adapted from PMID:21956911.)
Protein Function (UniProtKB)
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.
(UniProt, Q9VYS4)
Summary (Interactive Fly)

poly(A) polymerase acting on specific mRNA targets during late oogenesis and early embryogenesis - required at the final stage of oogenesis for metaphase during meiosis I arrest - interacts with Orb genetically and physically in an ovarian complex.

      sub mutants do not interact with alleles of γTub37C, αTub67C, msps, tacc or wisp.

      wisp is required to recruit or maintain known centrosomal proteins with two types of microtubule organising centers (MTOCs); the central MTOC that forms between the meiosis II tandem spindles and the centrosomes of the mitotic spindle.

      Both the wisp and aim mutant phenotypes suggest that these genes play important structural or regulatory roles in functions performed by microtubules.

      Maternal effect alleles cause embryos to arrest immediately following meiosis. Meiotic defects include perturbations of metaphase I arrest, and chromosome non-disjunction and loss. The astral array of microtubules between the two meiosis II spindles is small or missing, and lacks normal levels of gamma-tubulin and other centrosomal proteins normally present in this structure. After fertilization, long, wispy meiotic-like spindles form on the products of female meiosis. These embryos arrest with a small spindle formed on the haploid male pronucleus, as centrosomes of this spindle are lost in the nearby cytoplasm.

      Origin and Etymology
      Discoverer
      Etymology

      The gene is named "temprano", the Spanish word for "early", as mutant embryos show defects in the early syncytial stages.

      The gene is named "wispy" because of its mutant effects on spindle structures.
