Chromosome end protection plasticity revealed by Stn1p and Ten1p bypass of Cdc13p.

Petreaca RC, Chiu HC, Eckelhoefer HA, Chuang C, Xu L, Nugent CI

Genome stability necessitates a mechanism to protect the termini of linear chromosomes from inappropriate degradation or recombination. In many species this protection depends on 'capping' proteins that bind telomeric DNA. The budding yeast Cdc13p binds single-stranded telomeric sequences, prevents lethal degradation of chromosome ends and regulates telomere extension by telomerase. Two Cdc13-interacting proteins, Stn1p and Ten1p, are also required for ... [more]

POL12 STN1
Affinity Capture-Western
Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
