Identification
HMDB Protein ID CDBP02235
Secondary Accession Numbers Not Available
Name GPI mannosyltransferase 4
Description Not Available
Synonyms
  1. GPI mannosyltransferase IV
  2. GPI-MT-IV
  3. PIG-Z
  4. Phosphatidylinositol-glycan biosynthesis class Z protein
  5. SMP3 homolog
  6. hSMP3
Gene Name PIGZ
Protein Type Enzyme
Biological Properties
General Function Involved in transferase activity, transferring glycosyl groups
Specific Function Mannosyltransferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers a fourth mannose to some trimannosyl-GPIs during GPI precursor assembly. The presence of a fourth mannose in GPI is facultative and only scarcely detected, suggesting that it only exists in some tissues
