Involved in yeast cell wall biogenesis. Localizes to the cell periphery under conditions of vegetative growth. Expression is dependent upon the presence of the cell wall integrity pathway mitogen-activated protein kinase SLT2 and its downstream transcription factor RLM1. Hypersensitive to cell wall-perturbing agent calcofluor white (CFW) at 37 degrees Celsius. A similar phenotype is observed at 30 degrees Celsius, although the severity is decreased. Decreased expression of genes contributing to cell wall organization during vegetative growth. Overlaps completely with ORF YGR031W.
