bus-1 encodes an integral membrane O-acyltransferase; bus-1 mutants are resistant to colonization by Microbacterium nematophilum; a bus-1::GFP reporter fusion is expressed in rectal cells from late embryogenesis through adulthood with some adjacent neurons as well as two head neurons, probably amphidial, also showing expression.
Predicted to enable acyltransferase activity, transferring groups other than amino-acyl groups. Involved in morphogenesis of an epithelium. Located in membrane. Expressed in F cell; K cell; and U cell.
