| Abstrakt: | The five murine Zic genes encode multifunctional transcriptional regulator proteins important for a large number of processes during embryonic development. The genes and proteins are highly conserved with respect to the orthologous human genes, an attribute evidently mirrored by functional conservation, since the murine and human genes mutate to give the same phenotypes. Each ZIC protein contains a zinc finger domain that participates in both protein-DNA and protein-protein interactions. The ZIC proteins are capable of interacting with the key transcriptional mediators of the SHH, WNT and NODAL signalling pathways as well as with components of the transcriptional machinery and chromatin-modifying complexes. It is possible that this diverse range of protein partners underlies characteristics uncovered by mutagenesis and phenotyping of the murine Zic genes. These features include redundant and unique roles for ZIC proteins, regulatory interdependencies amongst family members and pleiotropic Zic gene function. Future investigations into the complex nature of the Zic gene family activity should be facilitated by recent advances in genome engineering and functional genomics. |
