Gfap and Osmr regulation by BRG1 and STAT3 via interchromosomal gene clustering in astrocytes.

abstract：:Organelle inheritance occurs during cell division. In Saccharomyces cerevisiae, inheritance of the vacuole, and the distribution of mitochondria and cortical endoplasmic reticulum are regulated by Ptc1p, a type 2C protein phosphatase. Here we show that PTC1/VAC10 controls the distribution of additional cargoes moved b...
