Abstract

The proto-oncogene product Vav plays a critical role in hematopoietic signal transduction. By using the yeast two-hybrid system, we identified a novel human protein, ENX-1, which interacts specifically with Vav both in vitro and in vivo. ENX-1 represents the human homolog of the Drosophila Enhancer of zeste gene, a member of the Polycomb group of genes, which are transcriptional regulators of homeobox gene expression. Interaction with ENX-1 suggests that Vav functions as an upstream element in the transcriptional regulation of homeobox genes, known to be important effectors in the hematopoietic system.
