|Other Names||GPI mannosyltransferase 4, 241-, GPI mannosyltransferase IV, GPI-MT-IV, Phosphatidylinositol-glycan biosynthesis class Z protein, PIG-Z, SMP3 homolog, hSMP3, PIGZ, SMP3|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|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.|
|Cellular Location||Endoplasmic reticulum membrane; Multi-pass membrane protein|
|Tissue Location||Widely expressed at low level, with highest level in brain and colon.|

The glycosylphosphatidylinositol (GPI) anchor is aglycolipid found on many blood cells that serves to anchor proteinsto the cell surface. This gene encodes a protein that is localizedto the endoplasmic reticulum, and is involved in GPI anchorbiosynthesis. As shown for the yeast homolog, which is a member ofa family of dolichol-phosphate-mannose (Dol-P-Man)-dependentmannosyltransferases, this protein can also add a side-branchingfourth mannose to GPI precursors during the assembly of GPIanchors.
