PER33

YLR064W
Protein that localizes to the endoplasmic reticulum; also associates with the nuclear pore complex; deletion extends chronological lifespan; highly conserved across species, orthologous to human TMEM33 and paralogous to Pom33p; protein abundance increases in response to DNA replication stress

Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Pom33 is an integral membrane protein of the yeast nuclear pore complex (NPC), and it is required for proper NPC distribution and assembly. To characterize the Pom33 NPC-targeting determinants, we performed immunoprecipitation experiments followed by mass spectrometry analyses. This identified a new Pom33 partner, the nuclear import factor Kap123. In vitro experiments revealed a direct interaction between the Pom33 C-terminal ... [more]
