Abstract

This dataset contains all biological replicates for immunoblots and immunofluorescence microscopy images associated with the manuscript "Coronavirus M protein disperses the trans-Golgi network and inhibits anterograde protein trafficking in the secretory pathway". These figures demonstrate that the SARS-CoV-2 M protein inhibits the ATF6 branch of the unfolded protein response but not the PERK or IRE1 branches. Additionally, the SARS-CoV-2 M protein localizes to the cis-Golgi while leading to dispersal of the trans-Golgi network and preventing anterograde trafficking of host proteins beyond the cis-Golgi. Furthermore, SARS-CoV-2 M recruits cholesterol to this site. This data provides a greater understanding of how SARS-CoV-2 M restructures the host secretory pathway which consequentially inhibits host protein trafficking and secretion, outlining a novel role for coronavirus M proteins beyond assembly and structure.
