Structural basis of the XPB-Bax1 complex as a dynamic helicase-nuclease machinery for DNA repair.

abstract：:Unlike short interfering RNAs (siRNAs), which are commonly designed to repress a single messenger RNA (mRNA) target through perfect base pairing, microRNAs (miRNAs) are endogenous small RNAs that have evolved to concurrently repress multiple mRNA targets through imperfect complementarity. MicroRNA target recognition i...
