Ypt32p regulates the translocation of Chs3p from an internal pool to the plasma membrane.

Abstract excerpt

The transport of the chitin synthase III, Chs3p, to the plasma membrane is temporally and spatially regulated. Chs3p is delivered to the plasma membrane at the beginning of the cell cycle, forming chitin rings, and at the end of the cell cycle, forming the primary septum. During the rest of the cell cycle, it is maintained in intracellular compartments, termed chitosomes that share characteristics with the late...
