Protein attributes

Sequence length	721 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Glycosyltransferase which participates in glycosylation of alpha-dystroglycan. May carry out the synthesis of glycoprotein and glycosphingolipid sugar chains. Has a higher activity toward alpha-dystroglycan than LARGE. Ref.6 Ref.8
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein By similarity Ref.8.
Tissue specificity	Widely expressed. Expressed at high level in placenta, pancreas and kidney compared to LARGE. Not expressed in brain. Ref.6 Ref.7
Sequence similarities	Belongs to the glycosyltransferase 8 family.
Sequence caution	The sequence AAG23791.1 differs from that shown. Reason: Frameshift at positions 496, 510 and 674. The sequence BAC03909.1 differs from that shown. Reason: Probable cloning artifact.
