- | [[ | + | [[https://www.uniprot.org/uniprot/TIF1B_HUMAN TIF1B_HUMAN]] Nuclear corepressor for KRAB domain-containing zinc finger proteins (KRAB-ZFPs). Mediates gene silencing by recruiting CHD3, a subunit of the nucleosome remodeling and deacetylation (NuRD) complex, and SETDB1 (which specifically methylates histone H3 at 'Lys-9' (H3K9me)) to the promoter regions of KRAB target genes. Enhances transcriptional repression by coordinating the increase in H3K9me, the decrease in histone H3 'Lys-9 and 'Lys-14' acetylation (H3K9ac and H3K14ac, respectively) and the disposition of HP1 proteins to silence gene expression. Recruitment of SETDB1 induces heterochromatinization. May play a role as a coactivator for CEBPB and NR3C1 in the transcriptional activation of ORM1. Also corepressor for ERBB4. Inhibits E2F1 activity by stimulating E2F1-HDAC1 complex formation and inhibiting E2F1 acetylation. May serve as a partial backup to prevent E2F1-mediated apoptosis in the absence of RB1. Important regulator of CDKN1A/p21(CIP1). Has E3 SUMO-protein ligase activity toward itself via its PHD-type zinc finger. Also specifically sumoylates IRF7, thereby inhibiting its transactivation activity. Ubiquitinates p53/TP53 leading to its proteosomal degradation; the function is enhanced by MAGEC2 and MAGEA2, and possibly MAGEA3 and MAGEA6.<ref>PMID:8769649</ref> <ref>PMID:9016654</ref> <ref>PMID:10347202</ref> <ref>PMID:11959841</ref> <ref>PMID:15882967</ref> <ref>PMID:16107876</ref> <ref>PMID:17178852</ref> <ref>PMID:16862143</ref> <ref>PMID:17079232</ref> <ref>PMID:17704056</ref> <ref>PMID:17942393</ref> <ref>PMID:18082607</ref> <ref>PMID:18060868</ref> <ref>PMID:20858735</ref> <ref>PMID:20864041</ref> <ref>PMID:20424263</ref> <ref>PMID:21940674</ref> |
