GPI transamidase complex is required for primordial germ cell migration and development in zebrafish

Proteins without transmembrane domains could be anchored to the cell surface for regulating various biological processes when covalently linked to glycosylphosphatidylinositol (GPI) molecules by the GPI transamidase (GPIT) complex. However, it remains poorly understood whether and how the GPIT complex affects primordial germ cell (PGC) development. In this study, we report the important roles of GPI transamidase in PGC migration and development in zebrafish embryos.
