Enables protein domain specific binding activity and protein phosphatase 2B binding activity. Involved in negative regulation of cell death and response to activity. Predicted to be located in aggresome; cytosol; and nucleoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in ovarian carcinoma. Orthologous to human CABIN1 (calcineurin binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
