FunctionComponent of the GPI transamidase complex. Essential for transfer of GPI to proteins, particularly for formation of carbonyl intermediates.
PathwayGlycolipid biosynthesis; glycosylphosphatidylinositol- anchor biosynthesis.
PtmThe disulfide bond between PIGK/GPI8 and PIGT is important for normal enzyme activity.
Sequence CautionSequence=AAD27715.1; Type=Frameshift; Positions=5, 27; Evidence= ; Sequence=AAQ88951.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence= ; Sequence=CAB57341.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence= ;
SimilarityBelongs to the PIGT family.
Subcellular LocationEndoplasmic reticulum membrane ; Single-pass type I membrane protein .
SubunitForms a complex with PIGK/GPI8, PIGS, PIGU and GPAA1/GAA1. Has a critical role in maintaining the complex by stabilizing the expression of GPAA1 and GPI8 and linking them to PIGS.
