Domain Architecture (Details)
InterPro domains unassigned to SynO:
The homeobox domain was first identified in a number of drosophila homeotic and segmentation proteins.ut is now known to be well-conserved in many other animals.ncluding vertebrates . Hox genes encode homeodomain-containing transcriptional regulators that operate differential genetic programs along the anterior-posterior axis of animal bodies . The domain binds DNA through a helix-turn-helix (HTH) structure. The HTH motif is characterised by two alpha-helices.hich make intimate contacts with the DNA and are joined by a short turn. The second helix binds to DNA via a number of hydrogen bonds and hydrophobic interactions.hich occur between specific side chains and the exposed bases and thymine methyl groups within the major groove of the DNA . The first helix helps to stabilise the structure. The motif is very similar in sequence and structure in a wide range of DNA-binding proteins (e.g..ro and repressor proteins.omeotic proteins.tc.). One of the principal differences between HTH motifs in these different proteins arises from the stereo-chemical requirement for glycine in the turn which is needed to avoid steric interference of the beta-carbon with the main chain: for cro and repressor proteins the glycine appears to be mandatory.hile for many of the homeotic and other DNA-binding proteins the requirement is relaxed.

Zinc finger domains .re nucleic acid-binding protein structures first identified in the Xenopus laevis transcription factor TFIIIA. These domains have since been found in numerous nucleic acid-binding proteins. A zinc finger domain is composed of 25 to 30 amino-acid residues including 2 conserved Cys and 2 conserved His residues in a C-2-C-12-H-3-H type motif. The 12 residues separating the second Cys and the first His are mainly polar and basic.mplicating this region in particular in nucleic acid binding. The zinc finger motif is an unusually small.elf-folding domain in which Zn is a crucial component of its tertiary structure. All bind 1 atom of Zn in a tetrahedral array to yield a finger-like projection.hich interacts with nucleotides in the major groove of the nucleic acid. The Zn binds to the conserved Cys and His residues. Fingers have been found to bind to about 5 base pairs of nucleic acid containing short runs of guanine residues. They have the ability to bind to both RNA and DNA.nd it has been suggested that the zinc finger may thus represent the original nucleic acid binding protein. It has also been suggested that a Zn-centred domain could be used in a protein interaction..g. in protein kinase C. Many classes of zinc fingers are characterized according to the number and positions of the histidine and cysteine residues involved in the zinc atom coordination. In the first class to be characterized.alled C2H2.he first pair of zinc coordinating residues are cysteines.hile the second pair are histidines.

Homeodomain proteins are transcription factors that share a related DNA binding homeodomain . The homeodomain was first identified in a number of Drosophila homeotic and segmentation proteins.ut is now known to be well conserved in many other animals.ncluding vertebrates. The domain binds DNA through a helix-turn-helix (HTH) structure. The HTH motif is characterised by two alpha-helices.hich make intimate contacts with the DNA and are joined by a short turn. The second helix binds to DNA via a number of hydrogen bonds and hydrophobic interactions.hich occur between specific side chains and the exposed bases and thymine methyl groups within the major groove of the DNA. The first helix helps to stabilise the structure. Many proteins contain homeodomains.ncluding Drosophila Engrailed.east mating type proteins.epatocyte nuclear factor 1a and HOX proteins.The homeodomain motif is very similar in sequence and structure to domains in a wide range of DNA-binding proteins.ncluding recombinases.yb proteins.ARP response regulators.uman telomeric proteins (hTRF1).aired domain proteins (PAX).east RAP1.entromere-binding proteins CENP-B and ABP-1.ranscriptional regulators (TyrR).raC-type transcriptional activators.nd tetracycline repressor-like proteins (TetR.acR.cdC) .
