The processing of RNAs transcribed by RNA polymerase II requires a cap-binding complex (CBC), consisting of NCBP1 and NCBP2. Here, the authors report an alternative CBC formed by NCBP1 and a previously uncharacterized protein, NCBP3 that is critical for RNA processing under cellular stress conditions.
