NCBI Protein Information
Exostosin family protein
NCBI Summary
Encodes a xyloglucan galactosyltransferase located in the membrane of Golgi stacks that is involved in the biosynthesis of fucose. It is also involved in endomembrane organization. It is suggested that it is a dual-function protein that is responsible for actin organization and the synthesis of cell wall materials.

UniProt Comments
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 (PubMed:12837954). Associates with other xyloglucan-synthesizing enzymes to form multiprotein complexes for xyloglucan synthesis in the Golgi (PubMed:25392066). 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 (PubMed:15863516). Involved in salt stress tolerance. Participates in the control of the expression of genes encoding for proteins involved in reactive oxygen species (ROS) detoxification under salt stress. May contribute to the maintenance of the proper organization of actin microfilaments during salt stress-induced ROS production (PubMed:23571490).
