Protein
Rik1-associated factor 2
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Function
Component of the rik1-associated E3 ubiquitin ligase complex that shows ubiquitin ligase activity and is required for histone H3K9 methylation. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting swi6/HP1 to methylated histones which leads to transcriptional silencing within centromeric heterochromatin, telomeric regions and at the silent mating-type loci. Has a role in both mitotic and meiotic chromosome segregation.
