CC -!- FUNCTION: Nuclear corepressor for KRAB domain-containing zinc finger
CC proteins (KRAB-ZFPs). Mediates gene silencing by recruiting CHD3, a
CC subunit of the nucleosome remodeling and deacetylation (NuRD) complex,
CC and SETDB1 (which specifically methylates histone H3 at 'Lys-9'
CC (H3K9me)) to the promoter regions of KRAB target genes. Enhances
CC transcriptional repression by coordinating the increase in H3K9me, the
CC decrease in histone H3 'Lys-9 and 'Lys-14' acetylation (H3K9ac and
CC H3K14ac, respectively) and the disposition of HP1 proteins to silence
CC gene expression. Recruitment of SETDB1 induces heterochromatinization.
CC May play a role as a coactivator for CEBPB and NR3C1 in the
CC transcriptional activation of ORM1. Also a corepressor for ERBB4.
CC Inhibits E2F1 activity by stimulating E2F1-HDAC1 complex formation and
CC inhibiting E2F1 acetylation. May serve as a partial backup to prevent
CC E2F1-mediated apoptosis in the absence of RB1. Important regulator of
CC CDKN1A/p21(CIP1). Has E3 SUMO-protein ligase activity toward itself via
CC its PHD-type zinc finger. Also specifically sumoylates IRF7, thereby
CC inhibiting its transactivation activity. Ubiquitinates p53/TP53 leading
CC to its proteosomal degradation; the function is enhanced by MAGEC2 and
CC MAGEA2, and possibly MAGEA3 and MAGEA6. Mediates the nuclear
CC localization of KOX1, ZNF268 and ZNF300 transcription factors. In
CC association with isoform 2 of ZFP90, is required for the
CC transcriptional repressor activity of FOXP3 and the suppressive
CC function of regulatory T-cells (Treg) (PubMed:23543754). Probably forms
CC a corepressor complex required for activated KRAS-mediated promoter
CC hypermethylation and transcriptional silencing of tumor suppressor
CC genes (TSGs) or other tumor-related genes in colorectal cancer (CRC)
CC cells (PubMed:24623306). Required to maintain a transcriptionally
CC repressive state of genes in undifferentiated embryonic stem cells
CC (ESCs) (PubMed:24623306). In ESCs, in collaboration with SETDB1, is
CC also required for H3K9me3 and silencing of endogenous and introduced
CC retroviruses in a DNA-methylation independent-pathway (By similarity).
CC Associates at promoter regions of tumor suppressor genes (TSGs) leading
CC to their gene silencing (PubMed:24623306). The SETDB1-TRIM28-ZNF274
CC complex may play a role in recruiting ATRX to the 3'-exons of zinc-
CC finger coding genes with atypical chromatin signatures to establish or
CC maintain/protect H3K9me3 at these transcriptionally active regions
CC (PubMed:27029610). {ECO:0000250|UniProtKB:Q62318,

CC -!- FUNCTION: (Microbial infection) Plays a critical role in the shutdown
CC of lytic gene expression during the early stage of herpes virus 8
CC primary infection. This inhibition is mediated through interaction with
CC herpes virus 8 protein LANA1. {ECO:0000269|PubMed:24741090}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27;
CC -!- PATHWAY: Protein modification; protein sumoylation.
CC -!- SUBUNIT: Interacts with SETX (PubMed:23149945). Oligomer; the RBCC
CC domain homotrimerizes and interacts with one molecule of KRAB to form
CC the KRAB-KAP1 corepressor complex. Binding to a KRAB domain is an
CC absolute requirement for silencing gene expression. Interacts with
CC CEBPB and NR3C1. Interacts with a number of KRAB-ZFP proteins including
CC ZNF10, ZFP53, ZFP68, ZNF382 and ZNF256. Interacts with NCOR1, NR3C1 and
CC CHD3. Interacts with CEBPB (via the RING-type and PHD-type zinc
CC fingers). Component of a ternary complex that includes TRIM28, a HP1
CC protein (CBX1, CBX3 OR CBX5), a KRAB domain-containing protein, and
CC DNA. Interacts with CBX5 (via the PxVxL motif); the interaction occurs
CC in interphase nuclei and competes for binding POGZ. Interacts with
CC POGZ; the interaction competes for interaction with CBX5. Interacts
CC with SETDB1; the interaction is enhanced by KAP1 sumoylation,
CC stimulates SETDB1 histone methyltransferase activity and gene
CC silencing. Interacts (via the PHD-type zinc finger) with UBE2I; the
CC interaction is required for sumoylation and repressor activity.
CC Component of the TRIM28/KAP1-ERBB4-MDM2 complex involved in connecting
CC growth factor and DNA damage responses. Interacts directly with ERBB4;
CC the interaction represses ERBB4-mediated transcription activity.
CC Interacts with MDM2; the interaction contributes to p53/TP53
CC inactivation. Component of the TRIM28/KAP1-MDM2-p53/TP53; involved in
CC regulating p53/TP53 stabilization and activity. Interacts (via the
CC leucine zipper alpha helical coiled-coil) with E2F1 (central region);
CC the interaction inhibits E2F1 acetylation and transcriptional activity.
CC Interacts with PPP1CA; the interaction dephosphorylates TRIM28 at Ser-
CC 824 and forms a complex at the p21 promoter site. Interacts with
CC PPP1CB; the interaction is weak but is increased on dephosphorylation
CC at Ser-824. Interacts with FES/FPS. Interacts with SMARCAD1. Interacts
CC with, and sumoylates IRF7. Interacts with MAGEC2. Part of a complex
CC composed of TRIM28, HDAC1, HDAC2 and EHMT2 (PubMed:21549307). Interacts
CC with AICDA (By similarity). Interacts (via the RBCC domain) with KOX1
CC (via the KRAB domain), ZNF268 (via the KRAB domain) and ZNF300 (via the
CC KRAB domain); the interactions increase KOX1, ZNF268 and ZNF300 nuclear
CC localization activities. The large PER complex involved in the histone
CC methylation is composed of at least PER2, CBX3, TRIM28, SUV39H1 and/or
CC SUV39H2; CBX3 mediates the formation of the complex. Interacts with
CC isoform 2 of ZFP90. Forms a complex with FOXP3 in the presence of
CC isoform 2 of ZFP90. Interacts with NR4A3; the interactions potentiates
CC NR4A3 activity on NurRE promoter (By similarity). Interacts

CC -!- TISSUE SPECIFICITY: Expressed in all tissues tested including spleen,
CC thymus, prostate, testis, ovary, small intestine, colon and peripheral
CC blood leukocytes. {ECO:0000269|PubMed:9016654}.
CC -!- DOMAIN: The HP1 box is both necessary and sufficient for HP1 binding.
CC {ECO:0000269|PubMed:18082607}.
CC -!- DOMAIN: The PHD-type zinc finger enhances CEBPB transcriptional
CC activity. The PHD-type zinc finger, the HP1 box and the bromo domain,
CC function together to assemble the machinery required for repression of
CC KRAB domain-containing proteins. Acts as an intramolecular SUMO E3
CC ligase for autosumoylation of bromodomain.
CC {ECO:0000269|PubMed:18082607}.
CC -!- DOMAIN: The RING-finger-B Box-coiled-coil/tripartite motif (RBCC/TRIM
CC motif) is required for interaction with the KRAB domain of KRAB-zinc
CC finger proteins. Binds four zinc ions per molecule. The RING finger and
CC the N-terminal of the leucine zipper alpha helical coiled-coil region
CC of RBCC are required for oligomerization.
CC {ECO:0000269|PubMed:18082607}.
CC -!- DOMAIN: Contains one Pro-Xaa-Val-Xaa-Leu (PxVxL) motif, which is
CC required for interaction with chromoshadow domains. This motif requires
CC additional residues -7, -6, +4 and +5 of the central Val which contact
CC the chromoshadow domain. {ECO:0000269|PubMed:18082607}.
CC -!- PTM: ATM-induced phosphorylation on Ser-824 represses sumoylation
CC leading to the de-repression of expression of a subset of genes
CC involved in cell cycle control and apoptosis in response to genotoxic
CC stress. Dephosphorylation by the phosphatases, PPP1CA and PP1CB forms,
CC allows sumoylation and expression of TRIM28 target genes.
CC {ECO:0000269|PubMed:16862143, ECO:0000269|PubMed:17178852,
CC ECO:0000269|PubMed:17942393, ECO:0000269|PubMed:20424263}.
CC -!- PTM: Sumoylation/desumoylation events regulate TRIM28-mediated
CC transcriptional repression. Sumoylation is required for interaction
CC with CHD3 and SETDB1 and the corepressor activity. Represses and is
CC repressed by Ser-824 phosphorylation. Enhances the TRIM28 corepressor
CC activity, inhibiting transcriptional activity of a number of genes
CC including GADD45A and CDKN1A/p21. Lys-554, Lys-779 and Lys-804 are the
CC major sites of sumoylation. In response to Dox-induced DNA damage,
CC enhanced phosphorylation on Ser-824 prevents sumoylation and allows de-
CC repression of CDKN1A/p21. {ECO:0000269|PubMed:16862143,

CC -!- PTM: Auto-ubiquitinated; enhanced by MAGEA2 and MAGEC2.
CC {ECO:0000269|PubMed:20864041}.
CC -!- PTM: Citrullinated by PADI4. {ECO:0000250|UniProtKB:Q62318}.
CC -!- PTM: ADP-ribosylated by SIRT6, promoting TRIM28/KAP1 interaction with
CC CBX5, thereby contributing to the packaging of LINE-1 retrotransposon
CC elements into transcriptionally repressive heterochromatin.
CC {ECO:0000250|UniProtKB:Q62318}.
CC -!- SIMILARITY: Belongs to the TRIM/RBCC family. {ECO:0000305}.
