General annotation (Comments)

Function

Involved in callose synthesis at the forming cell plate during cytokinesis. During plant growth and development, callose is found as a transitory component of the cell plate in dividing cells, is a major component of pollen mother cell walls and pollen tubes, and is found as a structural component of plasmodesmatal canals By similarity.

Catalytic activity

UDP-glucose + ((1->3)-beta-D-glucosyl)(n) = UDP + ((1->3)-beta-D-glucosyl)(n+1).

Subcellular location

Cell membrane; Multi-pass membrane protein Probable.

Sequence similarities

Belongs to the glycosyltransferase 48 family.

Sequence caution

The sequence BAA98065.1 differs from that shown. Reason: Erroneous gene model prediction.
