Protein sequence comparison.

Sequences of zebrafish (zcbfb), human (hCBFb), mouse (mCbfb) CBFβ proteins, and the Drosophila Bro and Bgb proteins are compared using the ClustalW program. Amino acid identities are in black boxes, and conserved amino acid changes are in shaded areas. The GenBank accession number for human CBFβ is AF294326, for mouse Cbfβ is Q08024, for Drosophila Bro is U22176, and for Bgb isU22177. Additional N-terminal sequences of Bro and Bgb are from Golling et al.17
