Abstract Insulator elements mediate intra- and inter-chromosomal interactions. The insulator protein CCCTC-binding factor (CTCF) is important for insulator function in several animals but a report in BMC Molecular Biology shows that Caenorhabditis elegans , yeast and plants lack CTCF. Alternative proteins may have a similar function in these organisms.
