Protein
Probable E3 ubiquitin-protein ligase dma1
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Function
Probable E3 ubiquitin-protein ligase which is a component of the spindle assembly checkpoint, required to prevent septum formation and premature exit from mitosis if spindle function is compromised. Inhibits the septation initiation netwok (SIN) during spindle checkpoint activation. The effect appears to be mediated through preventing the SIN activator, plo1 kinase, from localizing to the SPB.
Similarity
Belongs to the DMA1 family.
