| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Involved in the attachment of the Gal residue on the third xylosyl unit within the XXXG core structure of xyloglucan, the principal glycan that interlaces the cellulose microfibrils in plant cell wall. Interacts with actin and is required for the proper endomembrane organization and for the cell elongation. Not involved in the trafficking from the endoplasmic reticulum to the vacuoles. Ref.1 Ref.2 |
| Pathway | |
| Subcellular location | Golgi apparatus › Golgi stack membrane; Single-pass type II membrane protein. Ref.2 |
| Tissue specificity | Ubiquitous. Ref.1 |
| Domain | The cytoplasmic N-terminal domain interacts with actin, while the lumenal C-terminal domain contributes to the activity of xyloglucan galactosyltransferase. |
| Sequence similarities | Belongs to the glycosyltransferase 47 family. |
| Sequence caution | The sequence AAD21751.1 differs from that shown. Reason: Erroneous gene model prediction. |
