Predicted to enable protein phosphatase binding activity; protein phosphatase inhibitor activity; and pseudophosphatase activity. Predicted to be involved in several processes, including negative regulation of phosphoprotein phosphatase activity; negative regulation of stress granule assembly; and positive regulation of intrinsic apoptotic signaling pathway. Predicted to be active in mitochondrion. Orthologous to human STYXL1 (serine/threonine/tyrosine interacting like 1). [provided by Alliance of Genome Resources, Apr 2022]
