May have a role in modulating cell adhesion and glycosylation. Essential for development. Highest expression at vegetative and pre-aggregation stages. Slow growth, aberrant morphology and development. Produces a severe defect in spore formation. Cells are more adhesive. Alterations in glycosylation on membrane proteins and decreased gp130 and gp150 levels are observed. Belongs to the glycosyltransferase 8 family. Highly divergent.
