Faulhammer et al. found that Sac1p localized to the ER during exponential growth and was retained there by a direct interaction with an integral ER membrane protein called dolichol phosphate mannose synthase, or Dpm1p. When the researchers transferred these fast growing cells to nutrient-poor media, Sac1p moved to the Golgi within minutes./ W: Y7 y* P3 s
