ID:SDS3_HUMAN DESCRIPTION: RecName: Full=Sin3 histone deacetylase corepressor complex component SDS3; AltName: Full=45 kDa Sin3-associated polypeptide; AltName: Full=Suppressor of defective silencing 3 protein homolog; FUNCTION: Regulatory protein which represses transcription and augments histone deacetylase activity of HDAC1. May have a potential role in tumor suppressor pathways (By similarity). May function in the assembly and/or enzymatic activity of the mSin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes. SUBUNIT: Homodimer. Component of the SIN3 histone deacetylase (HDAC) corepressor complex. Interacts with SIN3A. Interaction with SIN3B enhances the interaction between SIN3B and HDAC1 to form a complex (By similarity). Interacts with HCFC1. Component of a mSin3A corepressor complex that contains SIN3A, SAP130, SUDS3/SAP45, ARID4B/SAP180, HDAC1 and HDAC2. INTERACTION: Q9HCU9:BRMS1; NbExp=2; IntAct=EBI-540496, EBI-714781; P51610:HCFC1; NbExp=2; IntAct=EBI-540496, EBI-396176; TISSUE SPECIFICITY: Expressed in various cancer cell ines. DOMAIN: The C-terminus is involved in transcriptional repression by HDAC-independent mechanisms. SIMILARITY: Belongs to the SDS3 family. SEQUENCE CAUTION: Sequence=BAB14685.1; Type=Erroneous initiation; Sequence=BAB15750.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
