CC   -!- FUNCTION: Required for CpsD phosphorylation. Involved in the regulation
CC       of capsular polysaccharide biosynthesis. May be part of a complex that
CC       directs the coordinated polymerization and export to the cell surface
CC       of the capsular polysaccharide (By similarity). {ECO:0000250}.
CC   -!- PATHWAY: Capsule biogenesis; capsule polysaccharide biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the CpsC/CapA family. {ECO:0000305}.
