[[https://www.uniprot.org/uniprot/HBP1_MOUSE HBP1_MOUSE]] Transcriptional repressor that binds to the promoter region of target genes. Plays a role in the regulation of the cell cycle and of the Wnt pathway. Binds preferentially to the sequence 5'-TTCATTCATTCA-3'. Binding to the H1F0 promoter is enhanced by interaction with RB1. Disrupts the interaction between DNA and TCF4 (By similarity).<ref>PMID:9178770</ref> [[https://www.uniprot.org/uniprot/SIN3A_MOUSE SIN3A_MOUSE]] Acts as a transcriptional repressor. Corepressor for REST. Interacts with MXI1 to repress MYC responsive genes and antagonize MYC oncogenic activities. Also interacts with MXD1-MAX heterodimers to repress transcription by tethering SIN3A to DNA. Acts cooperatively with OGT to repress transcription in parallel with histone deacetylation.<ref>PMID:8649810</ref> <ref>PMID:7889570</ref> <ref>PMID:10734093</ref>
