Most human GPI anchors have ethanolamine phosphate groups attached to their first and third mannose residues, but GPI anchors with ethanolamine phosphates attached to all three mannose residues have also been identified. Addition of the third ethanolamine phosphate can be catalyzed by a complex of PIG-F and a newly described human protein, GPI7. The donor of the ethanolamine phosphate for this reaction is unknown (Shishioh et al. 2005).
