Abstract This domain was first discovered in the doublesex proteins of Drosophila melanogaster and is also seen in proteins from Caenorhabditis elegans [PubMed9490411]. In D. melanogaste the doublesex gene controls somatic sexual differentiation by producing alternatively spliced mRNAs encoding related sex-specific polypeptides [PubMed8978051]. These proteins are believed to function as transcription factors on downstream sex-determination genes, especially on neuroblast differentiation and yolk protein genes transcription [PubMed1907913, PubMed3046751]. The DM domain binds DNA as a dimer, allowing the recognition of pseudopalindromic sequences [PubMed8978051, PubMed9927589, PubMed10898790]. The NMR analysis of the DSX DM domain [PubMed10898790] revealed a novel zinc module containing 'intertwined' CCHC and HCCC zinc-binding sites. The recognition of the DNA requires the carboxy-terminal basic tail which contacts the minor groove of the target sequence.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 1 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Cysteine-rich DNA binding domain, (DM domain) domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 1 hidden Markov models representing the Cysteine-rich DNA binding domain, (DM domain) superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
