The ribonuclease ZC3H12A stabilizes BRCA1 mRNA in DNA damage response.
ZC3H12A is an endoribonuclease that destabilizes target transcripts by recognizing stem-loop structures containing a pyrimidine-purine-pyrimidine loop. Here, we identify ZC3H12A as a constitutive stabilizer of BRCA1 mRNA that supports DNA repair capacity. Under basal conditions, depletion of ZC3H12A shortens the half-l...
