In mammalian cells, the 'Golgi reassembly and stacking protein' (GRASP) family has been implicated in Golgi stacking, but the broader functions of GRASP proteins are still unclear. The yeast Saccharomyces cerevisiae contains a single non-essential GRASP homolog called Grh1. However, Golgi cisternae in S. cerevisiae are not organized into stacks, so a possible structural role for Grh1 has been difficult to test. Here, we examined the localization and function of Grh1 in S. cerevisiae and in the… CONTINUE READING
