Generally, plasma membrane (PM) proteins are cotranslationally inserted into the endoplasmic reticulum (ER) and travel in vesicles via the Golgi apparatus to the PM. In the yeast Saccharomyces cerevisiae, the polytopic membrane protein Ist2p is encoded by an mRNA that is localized to the cortex of daughter cells. It has been suggested that IST2 mRNA localization leads to the accumulation of the protein at the PM of daughter cells. Since small- and medium-sized daughter cells only contain cortical, but not perinuclear ER, this implies the local translation of Ist2p specifically at the cortical ER. Here, we show that localization of constitutively expressed IST2 mRNA is required for delivery of Ist2p to the PM of daughter, but not mother cells and that it does not result in daughter-specific Ist2p accumulation. In contrast to a PM-located hexose transporter (Hxt1p) that follows the standard secretory pathway, the trafficking of Ist2p is independent of myosin-mediated vesicular transport. Furthermore, colocalization experiments in mutants of the secretory pathway demonstrate that trafficking of Ist2p does not require the classical secretory machinery. These data suggest the existence of a novel trafficking pathway connecting specialized domains of the ER with the PM.
