Contributes to the wild-type cellular response to nitrogen stress through signaling pathways that regulate the expression of genes involved in amino acid biosynthesis. Required for wild-type filamentous growth, cell growth, and cell-cell adhesion. Localizes to punctate patches in the plasma membrane that show extensive colocalization with SUR7. By the HOG1 MAPK, cell wall perturbations, and nitrogen stress. Expression is controlled by the MSS11 pseudohyphal growth transcription factor. N-glycosylated. Present with 1660 molecules/cell in log phase SD medium. Belongs to the SUR7 family.
