| abstractText | The human zinc finger protein 191 (ZNF191) is a Kruppel-like protein and can specifically interact with the widespread TCAT motif which constitutes the HUMTH01 microsatellite in the tyrosine hydroxylase (TH) gene (encoding the rate-limiting enzyme in the synthesis of catecholamines). Allelic variations of HUMTH01 are known to have a quantitative silencing effect on TH gene expression and to correlate with quantitative and qualitative changes in the binding by ZNF191. This factor has been isolated from bone marrow and promyelocytic leukemia cell lines indicating that ZNF191 also plays a role in hematopoiesis. Thus, ZNF191 could participate in the regulation of several genes implicated in different functions. Moreover, mice that are deficient in Zfp191, the murine homologue of ZNF191, have been shown to be severely retarded in development and to die approximately at embryonic day 7.5. In order to gain further insight into its biological functions, we have analysed the localisation of Zfp191 throughout mouse development. Expression was detected early during embryogenesis in ectodermal, endodermal, mesodermal and extra-embryonic tissues. In particular, Zfp191 was observed in the developing central nervous system. Interestingly, its expression levels were prominent in areas of proliferation such as the subventricular zone. Zfp191 expression pattern during development can account for the phenotypic features of Zfp191(-/-) embryos. |
