General annotation (Comments)

Function	Plays a role in cell wall integrity. Affects the cell wall polymer composition in the growing region of the cell. Ref.1
Subcellular location	Cell membrane; Single-pass type III membrane protein; Cytoplasmic side. Bud membrane; Single-pass type III membrane protein; Cytoplasmic side. Note: Localizes on the inner surface of the plasma membrane at the bud and in the daughter cell. Localizes at an incipient bud site in the cells with emerging buds, a bud tip in small- or medium-budded cells, and a cell periphery in large-budded cells. Ref.1 Ref.4
Sequence caution	The sequence CAA82180.1 differs from that shown. Reason: Frameshift at position 234.
