The nucleotide sequence of the murine Hox-D3 (Hox-4.1) gene reveals extensive identity with the human protein.

We report the sequence of the murine Hox-D3 gene, formerly referred to as Hox-4, Hox-4.1 and Hox-4A. This gene is located on murine chromosome 2 in the Hox-D complex. The predicted Hox-D3 protein comprises 417 amino acids and displays 95% identity to the human protein. We have demonstrated that Hox-D3 is expressed in the skin, kidney and thymus, but not in lung, liver, spleen or stomach.
