| UniProt functional annotation for Q8BR65 | |||
| UniProt code: Q8BR65. |
| Organism: | Mus musculus (Mouse). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus. | |
| Function: | Regulatory protein which represses transcription and augments histone deacetylase activity of HDAC1. May have a potential role in tumor suppressor pathways through regulation of apoptosis. 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 (By similarity). {ECO:0000250|UniProtKB:Q9H7L9, ECO:0000269|PubMed:11909966}. | |
| Subunit: | Interacts with HCFC1 (By similarity). 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. Component of a mSin3A corepressor complex that contains SIN3A, SAP130, SUDS3/SAP45, ARID4B/SAP180, HDAC1 and HDAC2. Interacts with USP17L2; the interaction is direct (By similarity). Interacts with FOXK2 (By similarity). {ECO:0000250|UniProtKB:Q9H7L9}. | |
| Subcellular location: | Nucleus {ECO:0000250|UniProtKB:Q9H7L9}. | |
| Tissue specificity: | Expressed in all newborn tissues tested, including brain, kidney and liver. {ECO:0000269|PubMed:11909966}. | |
| Domain: | The C-terminus is involved in transcriptional repression by HDAC-independent mechanisms. {ECO:0000250|UniProtKB:Q9H7L9}. | |
| Ptm: | Polyubiquitinated. 'Lys-63'-polyubiquitinated SUDS3 positively regulates histone deacetylation. Regulated through deubiquitination by USP17L2/USP17 that cleaves 'Lys-63'-linked ubiquitin chains (By similarity). {ECO:0000250|UniProtKB:Q9H7L9}. | |
| Similarity: | Belongs to the SDS3 family. {ECO:0000305}. | |
