Protein attributes
| Sequence length | 395 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Mediates GPI anchoring in the endoplasmic reticulum, by replacing a protein's C-terminal GPI attachment signal peptide with a pre-assembled GPI. During this transamidation reaction, the GPI transamidase forms a carbonyl intermediate with the substrate protein By similarity. |
| Pathway | Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis. |
| Subunit structure | Forms a complex with PIGT, PIGS, PIGU and GAA1 By similarity. |
| Subcellular location | Endoplasmic reticulum membrane; Single-pass type I membrane protein By similarity. |
| Post-translational modification | The disulfide bond between PIGK/GPI8 and PIGT is important for normal enzyme activity By similarity. |
| Sequence similarities | Belongs to the peptidase C13 family. |
