What's a GeneRIF?

In this study, we found that Cho1p, like mammalian PS synthases is inhibited by its product, PS. This suggests a simple mechanism of activating Cho1p at membrane contact sites (MCSs); PS transport out of the ER at MCSs will stimulate Cho1p activity in these regions.
Title: Phosphatidylserine synthesis at membrane contact sites promotes its transport out of the ER.
overexpression of CHO1 suppresses defects in the endocytic recycling pathway in flippase mutants. These results suggest that flippase-dependent vesicle formation is mediated by phospholipid flipping.
Title: Role of phosphatidylserine in phospholipid flippase-mediated vesicle transport in Saccharomyces cerevisiae.
phosphatidylserine synthase is phosphorylated on Ser(46) and Ser(47) by protein kinase A, which results in a higher amount of enzyme for the net effect of stimulating the synthesis of phosphatidylserine
