Our study aims to answer the question "Which functions of the Hsp70 class of molecular chaperones are essential for yeast to maintain a standard replicative life span?". To answer this question, we utilised the disparate functions of the Hsp70's Ssa1 and 2 and their paralog Ssa4 in a yeast strain that lacks Ssa1/2 but has an ectopically increased production of Ssa4. We have gathered data on the behaviour of several different markers for protein aggregation under different circumstances, as well as data on proteins from other classes of molecular chaperones. The bulk of the data is in the form of multichannel microscopy images from widefield microscopy, with a few sets of western blots of protein extracts.
Fluorescence microscopy of fixated yeast cells at mid-exponential growth. The samples have been stained with antibodies against Hsp42 (primary antibody: rabbit anti Hsp42, secondary antibody: goat anti rabbit Alexa Flour488) and counterstained with DAPI (datasets from 170505 and 170608) and antibodies against Actin (primary antibody: mouse anti- Act1, secondary antibody: goat anti mouse Alexa Flour 568) (dataset from 170518) or nucleoporin complexes (dataset from 170608) (primary antibody: mouse anti- Nsp1, secondary antibody: goat anti mouse Alexa Flour 568).
The dataset was collected through fluorescence microscopy.
