Protein attributes

Sequence length	394 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in the synthesis of the hemicellulose glucuronoxylan, a major component of secondary cell walls. Probably involved in the elongation of glucuronoxylan xylosyl backbone. Ref.5 Ref.6
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein Probable Ref.5.
Tissue specificity	Expressed in developing interfascicular fibers and xylem cells in stems and developing secondary xylem in roots. Ref.5
Sequence similarities	Belongs to the glycosyltransferase 43 family.
Sequence caution	The sequence AAD45998.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence AAF24965.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence AAM64331.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
