A homology domain shared between Drosophila optomotor-blind and mouse Brachyury is involved in DNA binding

Biochem Biophys Res Commun. 1992 Jul 31;186(2):918-25. doi: 10.1016/0006-291x(92)90833-7.


The distribution of sequence elements divides the optomotor-blind protein into three regions and is suggestive of a transcriptional regulatory role of this protein. The central region of Omb is homologous to the N-terminal half of the Brachyury protein. The conserved domain of Omb is here shown to possess general DNA binding affinity but has no significant similarity to recognized DNA binding motifs.
