Function

PIL1_YEAST Negative regulator of cell wall integrity (CWI) in unstressed cells, probably by inhibiting protein kinase PKH1/PHK2 activity and regulating their downstream CWI pathways PKC1-MAP kinase pathway and protein kinase YPK1 pathway. Activity may be regulated by the transient increase of sphingolipid long chain bases (LCBs) during heat stress.^[1]
