Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Function
Involved in chromosome cohesion during mitosis and meiosis by preventing premature dissociation of cohesin complex from centromeres after prophase, when most of cohesin complex dissociates from chromosomes arms. Required for faithful mitotic chromosome segregation and proper kinetochore orientation during meiosis I. In contrast to sgo1, it is dispensable for centromeric protection of rec8 during meiosis I as well as protection of rad21 during mitosis. Required to sense the lack of tension at centromeres during mitosis.
Similarity
Belongs to the shugoshin family.
