Sequence of murine Lhx9.A, Nucleotide and deduced amino acid sequence ofLhx9. Amino acids are indicated by single-letter code. The two in-frame ATG start codons areboxed. The sequence between the two possible start codons is in italics solely to indicate that based on homology with Lhx2, the second one is more likely to be used. LIM1, LIM2, and the hd are indicated by shading. The putative nuclearization signal is underlined.B, Comparison of murine Lhx9 with rat and chick Lhx2. The percentage of identity in each domain between gene products is indicated. GenBank/EMBL accession numbers: L06804 (rat Lhx2), L35566(chick Lh2B), and AB005882 (chick Lh2A).
