Doesn't feel right as a mapping for ATM checkpoint kinase for yeast
I agree, it sounds like a term that should be applied to multicellular organisms. Still, there is no taxon restrictions for this term. Nevertheless I have removed it.
I think it is ok to give this term to yeast Tel1. From papers (PMID:23672410, PMID:
22033189), you can find the description of yeast Tel1 involved in replicative senescence. I agreed that the definition of senescence might be different between mammals and yeasts. However, both ATM and Tel1 both play an important role in telomere maintenance, and this links them to replicative senescence in humans and yeasts (PMID:15610769, PMID:23672410).
p.s. I used to work on telomere capping in budding yeast, therefore, I am sure about the term "replicative senescence" is applicable in budding yeast.
