text PCBP4 binding to the 3'-UTR of the CDKN1A (p21) mRNA reduces half-life of the CDKN1A mRNA and the amount of CDKN1A protein. Upon DNA damage, TP53-mediated induction of CDKN1A is rapid, while the induction of PCBP4 is more gradual. It is hypothesized that, under prolonged stress, PCBP4-mediated down-regulation of CDKN1A may switch from G1 cell cycle arrest to G2 arrest, which may precede apoptosis (Scoumanne et al. 2011).
