General annotation (Comments)
| Function | Probable catalytic subunit of cellulose synthase terminal complexes ('rosettes'), required for beta-1,4-glucan microfibril crystallization, a major mechanism of the cell wall formation By similarity. |
| Catalytic activity | UDP-glucose + (1,4-beta-D-glucosyl)(n) = UDP + (1,4-beta-D-glucosyl)(n+1). |
| Cofactor | Binds 2 zinc ions per subunit By similarity. |
| Pathway | |
| Subcellular location | Cell membrane; Multi-pass membrane protein Probable. |
| Tissue specificity | Expressed in young plants, stems and flowers. Ref.4 |
| Developmental stage | Mostly expressed in cotyledons during all steps of embryogenesis, and decrease toward the bent-cotyledon stage. Ref.4 |
| Sequence similarities | Belongs to the glycosyltransferase 2 family. Plant cellulose synthase subfamily. Contains 1 RING-type zinc finger. |
