    Summary
    Involved in several processes, including maintenance of protein location in nucleus; male meiosis chromosome segregation; and meiotic sister chromatid cohesion. Located in chromosome; germ cell nucleus; and nuclear envelope. Is expressed in spermatocyte and spermatozoon. [provided by Alliance of Genome Resources, Dec 2024]

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. If ORD activity is more severely disrupted, achiasmate chromosomes with the normal amount of pericentric heterochromatin exhibit increased nondisjunction when oocytes age.
      Title: Heterochromatin-mediated association of achiasmate homologs declines with age when cohesion is compromised.
    2. Results suggest that association of orientation disruptor (ORD) with meiotic chromosomes during mid to late G2 is required to maintain sister-chromatid cohesion during prophase condensation.
      Title: Meiotic cohesion requires accumulation of ORD on chromosomes before condensation.
    3. Results suggest that orientation disruptor (ord) activity suppresses sister chromatid exchange and stimulates inter-homologue crossovers, promoting homologue bias during meiotic recombination in Drosophila.
      Title: The cohesion protein ORD is required for homologue bias during meiotic recombination.
