Description

Intracellular localization of GFP-Vps74 in S. cerevisiae pik1-83 temperature-conditional strain grown at restrictive temperature of 37C. In pik1-83 mutant after a 30 minute incubation at the restrictive temperature, GFP-Vps74 loses punctate localization and is mostly in the cytosol and nucleus. The Golgi-localized PtdIns 4-kinase in yeast is composed of the Pik1 catalytic subunit and a myristoylated calcium-binding protein, Frq1. Vps74 is essential to maintain glycosyltransferases in the Golgi and results in this study reveal a previously unrecognized PtdIns4P-binding site in Vps74/GOLPH3 family proteins and link Pik1 signaling to retention of Golgi-resident proteins. Cells grown in liquid medium were mounted in growth medium and 3D image stacks were collected at 0.4-µm z increments on a DeltaVision workstation (Applied Precision) based on an inverted microscope (IX-70; Olympus) using a 100× NA 1.4 oil immersion lens. Images were captured at 23C with a 12-bit CCD camera (CoolSnap HQ; Photometrics) and deconvolved using the iterative-constrained algorithm (Agard, 1984) and the measured point spread function. One image from the approximate center of z stack is shown in Fig1A Vps74/pik1-83 37C panel in J Cell Biol. 187: 967-975. 2009.
