Glycosylphosphatidylinositol transamidase (GPI-T) is a complicated, membrane-bound, multi-subunit enzyme that catalyzes an essential post-translational modification. This enzyme attaches GPI anchors to the C-termini of various proteins that contain a proper GPI-T signal sequence. Gpi8, Gaa1, Gpi16, Gpi17 and Gab1 are the five known subunits that may encompass the fungal GPI-T; Gpi8 is the catalytic subunit, but the functions of the other subunits remain essentially unknown. In humans, different GPI-T subunits are …
