Mannosyl_trans2

• PFAM accession number: PF04188
• Interpro abstract (IPR007315):

  This entry represents GPI mannosyltransferase 2, also known as PIG-V in humans or Gpi18 in fungi. PIG-V is a mannosyltransferase that transfers the second mannose in glycosylphosphatidylinositol (GPI) biosynthesis [ (PUBMED:15623507) (PUBMED:15720390) (PUBMED:17615295) ]. GPI is a glycolipid that anchors many proteins to the eukaryotic cell surface [ (PUBMED:15623507) ].

• GO process: GPI anchor biosynthetic process (GO:0006506)
• GO function: glycolipid mannosyltransferase activity (GO:0004376), alpha-1,6-mannosyltransferase activity (GO:0000009)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Mannosyl_trans2
