Protein attributes

Sequence length	1551 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	Recognizes glycoproteins with minor folding defects. Reglucosylates single N-glycans near the misfolded part of the protein, thus providing quality control for protein folding in the endoplasmic reticulum. Reglucosylated proteins are recognized by calreticulin for recycling to the endoplasmic reticulum and refolding or degradation. Ref.2 Ref.7 Ref.8
Cofactor	Calcium. Ref.5
Pathway	Protein modification; protein glycosylation.
Subunit structure	Monomer as well as in a tight complex with SEP15. Ref.4
Subcellular location	Endoplasmic reticulum lumen. Endoplasmic reticulum-Golgi intermediate compartment. Ref.6
Domain	N-terminal non-catalytic domain is assumed to mediate recognition of proteins with partial folding defects.
Sequence similarities	Belongs to the glycosyltransferase 8 family. Ref.2
biophysicochemical properties	Kinetic parameters: KM=44 µM for UDP-glucose (in the presence of 0.5 µM denatured acid phosphatase) Ref.2 Vmax=34 pmol/h/mg enzyme toward UDP-glucose (in the presence of 0.5 µM denatured acid phosphatase) Ref.2 pH dependence: Optimum pH is7.6-8.0.
