Polycomb group (PcG)-mediated repression ofC. elegansHox genes has not been demonstrated, and genes homologous to components of one of the PcG complexes (PRC1) have not been identified in theC. elegansgenome. We find that a mechanism of general Hox gene repression exists inC. elegans, carried out in part by SOP-2, a protein related to, but not orthologous with, any PcG protein.sop-2mutations lead to widespread ectopic expression of Hox genes and homeotic transformations. SOP-2 contains a SAM domain, a self-associating protein domain found in other repressors, including a core component of PRC1 and ETS transcription factors. Phylogenetic analysis indicates that this domain is more closely related to those of the ETS family than to those of PcG proteins. The results suggest that global repression of Hox genes has been taken over by a different branch of the SAM domain family during the evolution of nematodes.
