Predicted to enable protein serine/threonine phosphatase inhibitor activity. Predicted to be involved in mitotic G2/M transition checkpoint; positive regulation of cell growth; and positive regulation of proteasomal ubiquitin-dependent protein catabolic process. Predicted to be active in cytoplasm and nucleus. Orthologous to human PABIR1 (PP2A Aalpha (PPP2R1A) and B55A (PPP2R2A) interacting phosphatase regulator 1).
