Mammalian kinetochores contain the centromere-specific histone H3 variant CENP-A, whose incorporation into limited chromosomal regions may be important for centromere function and chromosome segregation during mitosis. However, regulation of CENP-A localization and its role have not been clear. Here we report that the fission yeast homolog SpCENP-A is(More)
The alternative splicing of mRNA is a critical process in higher eukaryotes that generates substantial proteomic diversity. Many of the proteins that are essential to this process contain arginine/serine-rich (RS) domains. ZRANB2 is a widely-expressed and highly-conserved RS-domain protein that can regulate alternative splicing but lacks canonical(More)
Virtually all eukaryotic cell functions and signaling pathways are regulated by protein phosphorylation. The Rad53 kinase plays crucial roles in the DNA damage response in Saccharomyces cerevisiae and is widely used as a surrogate marker for DNA damage checkpoint activation by diverse genotoxic agents. Most currently available assays for Rad53 activation(More)
