Organism
Drosophila melanogaster (Fruit fly)
Status
Functioni
May play a key role in egg organization. May be a transcriptional regulator having a role in chromatin remodeling in concert with Hira, a histone chaperone. Involved in chromosome segregation by affecting kinetochores function in the first meiotic division.2 Publications

Disruption phenotypei
Females exhibit disrupted chromosome segregation in the first meiotic division and produce very low numbers of viable progeny. This female sterility is partially suppressed when some oocytes undergo precocious anaphase. Analysis of the X chromosome of these progeny demonstrates they have inherited the two maternal X-chromosome homologs and have no paternal chromosome markers. This suggests that they developed from diploid gametes that underwent gynogenesis, a form of parthenogenesis that requires fertilization.1 Publication
