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 ...
Thus, the 60 amino acid DNA binding protein domain was named the homeodomain, while the 180 bp nucleotide sequence encoding it was named the homeobox. The homeobox gene clusters studied by Ed Lewis were named the Hox genes, although many more homeobox genes are encoded by animal genomes than those in the Hox gene clusters.
Retinal homeobox protein Rx also known as retina and anterior neural fold homeobox is a protein that in humans is encoded by the RAX gene. [5] The RAX gene is located on chromosome 18 in humans, mice, and rats.
Homeodomain proteins are transcription factors that share a DNA-binding domain called the homeodomain. [1] Changes in the expression and function of homeotic genes are responsible for the changes in the morphology of the limbs of arthropods as well as in the axial skeletons of vertebrates.

ZEB2 (previously also known as SMADIP1, SIP1) and its mammalian paralog ZEB1 belongs to the Zeb family within the ZF (zinc finger) class of homeodomain transcription factors. ZEB2 protein has 8 zinc fingers and 1 homeodomain. [7] The structure of the homeodomain shown on the right. ZEB2 interacts with receptor-mediated, activated full-length ...
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]
Paired-like homeodomain transcription factor 2 also known as pituitary homeobox 2 is a protein that in humans is encoded by the PITX2 gene. [ 5 ] [ 6 ] [ 7 ] Function
