The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

The acetyltransferase activity of San stabilizes the mitotic cohesin at the centromeres in a shugoshin-independent manner (2007, neutral): “Proteins such as Sgo1, PP2A, and Bub1 have been implicated in this protection (Salic et al., 2004; Tang et al., 2004; Kitajima et al., 2005, 2006; Riedel et al., 2006; Tang et al., 2006).”

Serine/threonine phosphatases: mechanism through structure. (2009, background): “For example, the B′ subunit, but not B or B′′, was thought to be specific for interacting with shugoshin (Kitajima et al., 2006; Riedel et al., 2006; Tang et al., 2006), a centromeric protein required for proper genome segregation (Gregan et al.”
Cohesin: its roles and mechanisms. (2009, background): “Whether shugoshins protect centromeric cohesin in mitosis by recruiting PP2A is still unclear, and there are conflicting reports as to whether PP2A’s recruitment to centromeres requires shugoshins (140) or vice versa (80, 174).”
