Protein Function (UniProtKB)
Required for the formation of cytoplasmic actin filament bundles in nurse cells, possibly by regulating both the polymerization and organization of actin filaments. Mutations in quail result in female sterility due to the disruption of cytoplasmic transport from the nurse cells into the oocyte late in oogenesis.
(UniProt, Q23989)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
fs(2)A12
Homozygous females anatomically normal; lay foreshortened eggs with truncated anterior tip and short fat chorionic filaments. Eggs similar to stage-11 oocytes, some with adhering follicle and nurse cells. A few eggs lack stainable chromatin; most have one to three large spherical masses of fragmented chromosomes or tripolar spindles and abnormally elongated mitotic figures.
qua: quail (T. Schupbach)
Female sterile; nurse-cell contents not transported into the egg; follicle cells produce normal chorion around tiny eggs, which remain unfertilized.

qua is enriched in border follicle cells relative to follicle cells.

qua transcripts are abundant in male testes and female ovaries and in early embyros and are detected at very low levels at other times of development by northern blots. qua transcripts are detected in nurse cells and in the oocyte by in situ hybridization.

Additional Descriptive Data

In oocyte stages S8-S10A, qua protein colocalizes with the subcortical actin filament network in the nurse cells and the oocyte. It is also present in the cytoplasm of nurse cells. Occasionally, it localizes to ring canals. In stage S10B, the levels of qua protein rise significantly and it is found along the length of the newly assembled actin filament bundles in the nurse cell cytoplasm.

    dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

    dsRNA made from templates generated with primers directed against this gene is tested in an RNAi screen for effects on actin-based lamella formation.

    qua protein can bind and bundle filamentous actin in vitro, regardless of the concentration of calcium ions.

    Like vertebrate villin, qua product can bundle actin filaments in vitro.

    The villin-like product of the qua locus is required for the formation of cytoplasmic actin filament bundles in nurse cells, possibly by regulating both the polymerization and organization of actin filaments as has been demonstrated for vertebrate villin in vitro.

    Mutations at the qua locus cause defects in midoogenesis.
