| abstractText | Onecut (OC) transcription factors are evolutionarily conserved proteins with important developmental functions. They contain a bipartite DNA-binding domain composed of a single cut domain associated with a divergent homeodomain. The human genome contains three Onecut paralogues, Hnf6 (also called Oc1), Oc2 and Oc3. We describe here the cloning of mouse (m) OC-2 and its expression pattern in the mouse embryo. The mOc2 gene was localized on chromosome 18. Analysis of the mOC-2 amino acid sequence revealed overall identities of 67% with mHNF-6 and of 56% with mOC-3, and the presence of functional domains delineated earlier in HNF-6. The sequence of the 153 residue-long cut-homeodomain was very conserved, as it was 92% identical to that of mHNF-6 and 89% identical to that of mOC-3. In situ hybridization showed expression of mOc2 in the developing nervous system and gut endoderm. Like Hnf6, Oc2 was expressed in developing liver and pancreas. As many genes that are targeted by Onecut factors are recognized by both OC-2 and HNF-6, this overlap of expression patterns may have functional implications. |
