Protein attributes

Sequence length	1516 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 By similarity.
Cofactor	Calcium or manganese.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Endoplasmic reticulum lumen. Endoplasmic reticulum-Golgi intermediate compartment Ref.5.
Tissue specificity	Higher levels in kidney, pancreas, heart, and skeletal muscle. Ref.1
Sequence similarities	Belongs to the glycosyltransferase 8 family.
Caution	Has no enzymatic activity towards unfolded RNase B or thyroglobulin (Ref.1).
