Little is known about the origin of the inductive signal that translates the amputation stress into a cooperative cellular response. By studying the process underlying the reformation of lost body parts in the anthozoan cnidarian Nematostella vectensis, we identified a regeneration-inducing structure that, via a tissue crosstalk, is responsible...

The shelterin proteins protect telomeres against activation of the DNA damage checkpoints and recombinational repair. We show here that a dimer of the shelterin subunit TRF2 wraps ∼ 90 bp of DNA through several lysine and arginine residues localized around its homodimerization domain. The expression of a wrapping-deficient TRF2 mutant, named...
