Predicted to enable phosphoprotein phosphatase activity and protein phosphatase activator activity. Involved in negative regulation of peptidyl-threonine phosphorylation. Predicted to be part of protein phosphatase type 2A complex. Predicted to be active in cytosol and nucleus. Human ortholog(s) of this gene implicated in autosomal dominant non-syndromic intellectual disability 35. Orthologous to human PPP2R5D (protein phosphatase 2 regulatory subunit B'delta).
