GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. Together, the Hrr25 central domain and Mam1 form a novel, contiguous embellishment to the Hrr25 kinase domain that affects Hrr25 conformational dynamics and enzyme kinetics.
    Title: Structure of the Saccharomyces cerevisiae Hrr25:Mam1 monopolin subcomplex reveals a novel kinase regulator.
  2. We show that monopolin subunit Mam1 binds tightly to Hrr25, a highly conserved casein kinase 1 delta/varepsilon, and recruits it to meiosis I centromeres. Hrr25 kinase activity and Mam1 binding are both essential for monopolar attachment.
    Title: Monopolar attachment of sister kinetochores at meiosis I requires casein kinase 1.
  3. Study finds that the Aurora B kinase Ipl1 regulates kinetochore-microtubule attachment during both meiotic divisions and that a complex known as the monopolin complex ensures that the protein kinase coorients sister chromatids during meiosis I.
    Title: Kinetochore orientation during meiosis is controlled by Aurora B and the monopolin complex.

  • Monopolin; meiosis-specific kinetochore-associated protein involved in monopolar attachment of sister kinetochores to the meiotic spindle; subunit of monopolin, a complex that prevents biorientation of sister kinetochores to ensure homolog biorientation during meiosis I; regulates the conformation, enzyme kinetics and substrate specificity of the Dsn1p kinase, Hrr1p; expressed only during the first meiotic division
