Differential expression and function of members of the zfh-1 family of zinc finger/homeodomain repressors.

ABSTRACT: zfh-1 is a zinc finger/homeodomain transcriptional repressor in Drosophila that regulates differentiation of muscle and gonadal cells and is also expressed in the central nervous system (CNS). Binding sites for zfh-1 overlap with those for snail, and like snail, it recruits the corepressor CtBP-1. The protein ZEB-1 appears to be a vertebrate homologue of zfh-1 and is expressed in several tissues including muscle, CNS, and T lymphocytes, and during skeletal differentiation. Mutation of the ZEB-1 gene led to a severe T cell phenotype and skeletal defects but, interestingly, no defects were evident in other ZEB-1-expressing tissues. These results suggested that another ZEB-1-related factor may compensate for the loss of ZEB-1 in other tissues. Here, we characterize such a ZEB-1-related protei
