Sds3

Sds3
PFAM accession number:PF08598
Interpro abstract (IPR013907):

Repression of gene transcription is mediated by histone deacetylases containing repressor-co-repressor complexes, which are recruited to promoters of target genes via interactions with sequence-specific transcription factors. The co-repressor complex contains a core of at least seven proteins [(PUBMED:15451426)]. This entry represents the conserved region found in Sds3, Dep1 and BRMS1-homologue p40 proteins.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Sds3
