Research Abstract |
We found that Moa1, which is indispensable factor to establish fusion of sister kinetochores during meiosis I, can bind to Polo like kinase (Plo1). Through several analyses, I showed that Plo1 plays crucial role to make sister kinetochores fusion state via its kinase activity. In addition, I found that SPO13 gene, which has been shown to be required for reductional segregation in budding yeast and acts with Polo like kinase (CDC5), could suppress equational segregation phenotype in moa1 delta cells. This suggests that although they do not share the sequence homology, SPO13 is functional homolog of Moa1 in budding yeast.
