Predicted to contribute to GPI anchor binding activity. Predicted to be involved in attachment of GPI anchor to protein; protein localization to cell surface; and regulation of receptor signaling pathway via JAK-STAT. Predicted to be located in plasma membrane. Predicted to be part of GPI-anchor transamidase complex. Orthologous to human PIGU (phosphatidylinositol glycan anchor biosynthesis class U).
