Comparison of structures of porcine LHX2 and LHX3. LIM-homeodomain transcription factors are composed of two LIM domains (LIM1 and LIM2) and a DNA-binding homeodomain (HD), with numbered amino acid positions (LHX2 and LHX3a). LHX3a and LHX3b are composed of 401 (a) and 403 (b) amino acids, respectively. The homology (%) of the domains is indicated between the diagrams.
