Homeobox genes encode homeodomain protein products that are transcription factors sharing a characteristic protein fold structure that binds DNA to regulate expression of target genes. [ 3 ] [ 4 ] [ 2 ] Homeodomain proteins regulate gene expression and cell differentiation during early embryonic development, thus mutations in homeobox genes can ...
Rax (Retina and Anterior Neural Fold Homeobox) is a gene in the OAR (Otx, Arx,& Rax) subgroup of the paired-like homeodomain family of transcription factors. Discovered in 1997, [8] the Rax gene is known to contribute to the development of the retina, hypothalamus, pineal gland and pituitary gland. [9]
The homeodomain is a 60-amino-acid-long DNA-binding domain (encoded by its corresponding 180-base-pair DNA sequence, the homeobox). This amino acid sequence folds into a "helix-turn-helix" (i.e. homeodomain fold) motif that is stabilized by a third helix.
Iroquois-class homeodomain protein IRX-1, also known as Iroquois homeobox protein 1, is a protein that in humans is encoded by the IRX1 gene. [ 5 ] [ 6 ] All members of the Iroquois (IRO) family of proteins share two highly conserved features, encoding both a homeodomain and a characteristic IRO sequence motif . [ 7 ]

The Lim gene family is a subfamily of homeobox genes. [7] The homeobox genes are essential in organizing the body plan of an organism and all contain the same conserved homeodomain of amino acids. [8] Evidence that Lim-1 is essential to a developing organism is its conservation throughout evolution and presence in a variety of organisms. [7]
The protein encoded by this gene is a transcription factor that is highly expressed in the liver and is involved in the regulation of the expression of several liver-specific genes. [9] Mutations in the HNF1A gene have been known to cause diabetes. [10] The HNF1A gene also contains a SNP associated with increased risk of coronary artery disease ...
OB-fold domains range between 70 and 150 amino acids in length. [11] OB-folds bind single-stranded DNA, and hence are single-stranded binding proteins. [11] OB-fold proteins have been identified as critical for DNA replication, DNA recombination, DNA repair, transcription, translation, cold shock response, and telomere maintenance. [12]
