Technical Data
DPM1 (Dolichyl-phosphate mannosyltransferase polypeptide 1, catalytic subunit, RP23-391M18.1, AI118379, AI194292, OTTMUSP00000017164, dolichol monophosphate mannose synthase, dolichyl-phosphate mannosyltransferase polypeptide 1)
Dolichol-phosphate mannose (DPM1) serves as a donor of mannosyl residues on the lumenal side of the endoplasmic reticulum (ER). Defective surface expression of GPI-anchored proteins occurs when there is a lack of DPM1. DPM1 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.

Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:64,000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
