DHD_Dac cd21081
Dachshund-homology domain found in the retinal determination protein Dachshund and similar ...
 50-144 1.76e-74

Dachshund-homology domain found in the retinal determination protein Dachshund and similar proteins; Dachshund proteins act as transcription factors involved in the regulation of organogenesis. They may be a regulator of SIX1, SIX6 and probably SIX5. The Dachshund-homology domain (DHD), also known as the N-terminal Ski/Sno/Dac domain, adopts a mixed alpha/beta structure containing a helix-turn-helix motif, similar to features found in the forkhead/winged-helix family of DNA binding proteins. It contains a conserved CLPQ motif and can bind co-factors. Its structure suggests that it may also bind DNA. It has been postulated that Dachshund proteins may bind to chromatin DNA via their DHD domains.

SKI/SNO/DAC family; This family contains a presumed domain that is about 100 amino acids long. All members of this family contain a conserved CLPQ motif. The c-ski proto-oncogene has been shown to influence proliferation, morphological transformation and myogenic differentiation. Sno, a Ski proto-oncogene homolog, is expressed in two isoforms and plays a role in the response to proliferation stimuli. Dachshund also contains this domain. It is involved in various aspects of development.

 52-141 7.60e-25

Dachshund-homology domain found in the Ski/Sno/Dac family of transcriptional regulators; The Dachshund-homology domain (DHD), also known as the N-terminal Ski/Sno/Dac domain, adopts a mixed alpha/beta structure containing a helix-turn-helix motif, similar to features found in the forkhead/winged-helix family of DNA binding proteins. It contains a conserved CLPQ motif and can bind co-factors. Its structure suggests that it may also bind DNA. Members of this family include the Ski protein, Ski-like protein (Sno), and Dachshund proteins. Ski may play a role in terminal differentiation of skeletal muscle cells but not in the determination of cells to the myogenic lineage. It functions as a repressor of transforming growth factor-beta (TGF-beta) signaling. Ski-like protein, also known as SKIL or Sno, is the ski proto-oncogene homolog. It may have regulatory roles in cell division or differentiation in response to extracellular signals. Dachshund proteins are essential components of a regulatory network controlling cell fate determination. They have been implicated in eye, limb, brain, and muscle development.

Dachshund-homology domain found in SKI family transcriptional corepressors, Skor1, Skor2 and similar proteins; Skor1, also known as functional Smad-suppressing element on chromosome 15 (Fussel-15), LBX1 corepressor 1, or ladybird homeobox corepressor 1, acts as a transcriptional corepressor of LBX1 and inhibits BMP signaling. Skor2, also known as functional Smad-suppressing element on chromosome 18 (Fussel-18), LBX1 corepressor 1-like protein, or ladybird homeobox corepressor 1-like protein, exhibits transcriptional repressor activity. It acts as a transforming growth factor-beta (TGF-beta) antagonist in the nervous system. The Dachshund-homology domain (DHD), also known as the N-terminal Ski/Sno/Dac domain, adopts a mixed alpha/beta structure containing a helix-turn-helix motif, similar to features found in the forkhead/winged-helix family of DNA binding proteins. It contains a conserved CLPQ motif and can bind co-factors. Its structure suggests that it may also bind DNA.
