Protein attributes

Sequence length	1448 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Selectively reglucosylates unfolded glycoproteins, thus providing quality control for protein transport out of the ER. Unfolded, denatured glycoproteins are substantially better substrates for glucosylation by this enzyme than are the corresponding native proteins. This protein and transient glucosylation may be involved in monitoring and/or assisting the folding and assembly of newly made glycoproteins, in order to identify glycoproteins that need assistance in folding from chaperones. Ref.1
Cofactor	Calcium or manganese. Ref.1
Pathway	Protein modification; protein glycosylation.
Subunit structure	Monomer. Ref.1
Subcellular location	Endoplasmic reticulum lumen Ref.1.
Post-translational modification	Glycosylated. Ref.1
Sequence similarities	Belongs to the glycosyltransferase 8 family.
