Plays a role in haploid invasive growth under conditions of nutrient insufficiency, suggesting that the function of the MEMO1 family in cell motility/invasion is conserved across species. Is actively exported from the nucleus. Expression is induced by mild heat-stress on a non-fermentable carbon source (PubMed:14561723). Expression is also induced upon entry into stationary phase and upon nitrogen deprivation (PubMed:11102521). Expression is repressed by inosine and choline in an OPI1-dependent manner (PubMed:12871953). Is synthetic lethal with PLC1. Present with 339 molecules/cell in log phase SD medium. Belongs to the MEMO1 family.
