N-acetylglucosaminyl transferase component (IPR007720)

Short name: GlcNAc_Gpi1

Family relationships

None.

Description

Glycosylphosphatidylinositol (GPI) represents an important anchoring molecule for cell surface proteins. The first step in its synthesis is the transfer of N-acetylglucosamine (GlcNAc) from UDP-N-acetylglucosamine to phosphatidylinositol (PI). This chemically simple step is genetically complex because three or four genes are required in both Saccharomyces cerevisiae (GPI1, GPI2 and GPI3) and mammals (GPI1, PIG A, PIG H and PIG C), respectively [PMID: 11849707].
