  Domain Name: PIG-S
Phosphatidylinositol-glycan biosynthesis class S protein. PIG-S is one of several key, core, components of the glycosylphosphatidylinositol (GPI) trans-amidase complex that mediates GPI anchoring in the endoplasmic reticulum. Anchoring occurs when a protein's C-terminal GPI attachment signal peptide is replaced with a pre-assembled GPI. Mammalian GPITransamidase consists of at least five components: Gaa1, Gpi8, PIG-S, PIG-T, and PIG-U, all five of which are required for function. It is possible that Gaa1, Gpi8, PIG-S, and PIG-T form a tightly associated core that is only weakly associated with PIG-U. The exact function of PIG-S is unclear.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
