    Description

    Amino acid replacement: H520Y.

    (Lasko, 2000.2.1)

    Amino acid replacement: H520Y. Nucleotide substitution is of TAT for CAT, in the 425 amino stretch that is highly similar among DEAD-box proteins.

        vasAS does not modify PEV, as assayed using the y PEV reporter line P{SUPor-P}B079.

        (Gracheva et al., 2009)

        Very few nuage clusters and particles remain in homozygous nurse cells. Nuage is completely disrupted in the spermatocytes of mutant males.

        (Snee and Macdonald, 2004)

        Reduced posterior vas localization in the oocyte.
