CC   -!- FUNCTION: Necessary for the synthesis of poly-beta-1,6-N-acetyl-D-
CC       glucosamine (PNAG, also referred to as PIA), a biofilm adhesin
CC       polysaccharide. Is required for full IcaA N-
CC       acetylglucosaminyltransferase activity (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the IcaD family. {ECO:0000305}.
