Rabbit anti-Human DPM1 Polyclonal Antibody

Uniprot Id

O60762

Target Species

Human

Target Name

DPM1

Target Full Name

Dolichol-phosphate mannosyltransferase subunit 1

Target Function

Transfers mannose from GDP-mannose to dolichol monophosphate to form dolichol phosphate mannose (Dol-P-Man) which is the mannosyl donor in pathways leading to N-glycosylation, glycosyl phosphatidylinositol membrane anchoring, and O-mannosylation of proteins; catalytic subunit of the dolichol-phosphate mannose (DPM) synthase complex.

Target Involvement

Congenital disorder of glycosylation 1E (CDG1E)

Target Subcellular Location

Endoplasmic reticulum.

Target Protein Families

Glycosyltransferase 2 family

Target Background

Dolichol-phosphate mannose (Dol-P-Man) serves as a donor of mannosyl residues on the lumenal side of the endoplasmic reticulum (ER). Lack of Dol-P-Man results in defective surface expression of GPI-anchored proteins. Dol-P-Man is synthesized from GDP-mannose and dolichol-phosphate on the cytosolic side of the ER by the enzyme dolichyl-phosphate mannosyltransferase. Human DPM1 lacks a carboxy-terminal transmembrane domain and signal sequence and is regulated by DPM2. Mutations in this gene are associated with congenital disorder of glycosylation type Ie. Alternative splicing results in multiple transcript variants.
