Involved in attachment of GPI anchor to protein. Located in endoplasmic reticulum. Part of GPI-anchor transamidase complex. Orthologous to human GPAA1 (glycosylphosphatidylinositol anchor attachment 1).
SGD Description
Subunit of the GPI:protein transamidase complex; removes the GPI-anchoring signal and attaches GPI (glycosylphosphatidylinositol) to proteins in the ER; human homolog GPAA1 can complement growth defects of yeast thermosensitive mutant at restrictive temperature
