Supplementary information

PIGK also known as phosphatidylinositol glycan anchor biosynthesis class K functions as an essential component of the glycosylphosphatidylinositol (GPI) transamidase complex. This protein carries a mass of approximately 37 kDa. You find PIGK in the endoplasmic reticulum across various cell types where it assists in the post-translational modification processes required for protein anchoring to cell membranes.
Biological function summary

The GPI transamidase complex which includes PIGK facilitates the attachment of proteins to the cell membrane via GPI anchors. This activity is a critical post-translational modification essential for the functionality and localization of these proteins. Within this complex PIGK operates alongside other components such as PIGT and GPAA1 to ensure correct positioning and attachment of GPI-anchored proteins.

Pathways

PIGK contributes to the biosynthesis and remodeling of GPI-anchored proteins impacting the GPI-anchor biosynthesis pathway itself. This pathway plays an integral role in cellular processes that involve anchoring proteins like CD55 and CD59 which are important for membrane dynamics and cell surface interactions. As part of these pathways PIGK's function links closely with other proteins in the remodeling process ensuring proper protein placement and functionality.

PIGK's role in GPI-anchor biosynthesis links it to various inherited GPI deficiencies. A disruption in PIGK function may contribute to neurological symptoms and developmental disorders like hyperphosphatasia with mental retardation syndrome (HPMRS). The connection between PIGK and diseases often involves interactions with other components of the GPI biosynthesis pathway such as PIGA highlighting the significance of PIGK in maintaining cellular and physiological homeostasis.

Product protocols

Target data

Component of the GPI transamidase complex, necessary for transfer of GPI to proteins (PubMed : 34576938). 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.
