We have identified zfh-4, a new member of a recently recognized zinc finger-homeodomain (zfh) family of putative transcription factors. Zfh-4 expression is prominent in developing muscle and brain. In both tissues, zfh-4 RNA levels are highest embryonically, then decrease gradually to barely detectable levels in adults. In myogenic cell lines, far more zfh-4 is expressed in proliferating myoblasts than in myotubes, suggesting a cellular basis for the developmental regulation observed in vivo. In contrast, zfh-4 RNA in brain is more abundant in postmitotic cells of the marginal zone than in proliferating cells of the ventricular zone. Within the brain, zfh-4 RNA is regionally localized: expression is highest in midbrain, readily detectable in hindbrain, and very low in cerebral cortex. Its patterns of expression, and its homology to known DNA binding proteins, support the idea that zfh-4 may be a regulator of gene expression in developing brain and muscle.
