The formation of multiprotein complexes is l'ordre du jour in regulatory pathways. In this issue of Oncogene, Reale et al. report the formation of a particularly sophisticated complex of two important regulatory enzymes, DNMT1 (DNA methyltransferase-1) and PARP-1 (poly(ADP-ribose)polymerase-1). The former evolved with a specific sequence motif binding the enzymatic product of the latter. The product, poly(ADP-ribose), bonds the two partners into a heterodimeric complex and, as a consequence, the catalytic function of DNMT1 is silenced. Thus, PARP-1 becomes a conditional negative regulator of DNMT1. In a larger perspective, Reale et al. highlight the potential role of PARP-1 as a co-regulator of DNA methylation leading to epigenetic reprogramming of cancer cells.
