추가 정보

This supplementary information is collated from multiple sources and compiled automatically.

KAP1 also known as TRIM28 or TIF1β is a multifunctional protein involved in transcriptional regulation. It has a molecular weight of approximately 87 kDa. This protein is expressed in a wide variety of human tissues where it plays a role as a co-repressor for KRAB domain-containing zinc finger proteins. KAP1 recruits various epigenetic modifiers to silence transcription and this activity depends on its phosphorylation status. You might explore KAP1 using KAP1 ELISA kits and study its post-translational modifications like phosphorylation in various conditions.

Biological function summary

KAP1 acts as a scaffold protein facilitating the assembly of large protein complexes that include chromatin remodelers and histone deacetylases. It is significant in maintaining chromatin structure and mediating gene silencing. KAP1 phosphorylation serves as a switch between its roles in transcriptional repression and activation. This protein also interacts with heterochromatin protein 1 (HP1) and other TRIM family proteins playing an important role in genomic stability by controlling gene expression and repair mechanisms.

Pathways

KAP1 participates actively in p53 and DNA damage response pathways. In the p53 pathway KAP1 regulates genes involved in the cell cycle and apoptosis acting in conjunction with the p53 protein. Within the DNA damage response KAP1 modulates the repair of double-strand breaks by interacting with proteins like ATM kinase influencing cellular sensitivity to genotoxic stress. These pathways highlight its importance in maintaining cellular homeostasis and response to external stimuli.

KAP1 has known connections with cancer and neurological disorders due to its regulatory effects on gene expression and genome stability. In cancer aberrant KAP1 activity can lead to unregulated cell proliferation and survival often involving changes in its interaction with the p53 protein. In neurological disorders dysregulation of KAP1 is associated with impaired neural development and neurodegeneration. Altogether these associations highlight KAP1 as a potential target for therapeutic interventions in related diseases.

타겟 정보

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 a 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 proteasomal degradation; the function is enhanced by MAGEC2 and MAGEA2, and possibly MAGEA3 and MAGEA6. Mediates the nuclear localization of KOX1, ZNF268 and ZNF300 transcription factors. In association with isoform 2 of ZFP90, is required for the transcriptional repressor activity of FOXP3 and the suppressive function of regulatory T-cells (Treg) (PubMed : 23543754). Probably forms a corepressor complex required for activated KRAS-mediated promoter hypermethylation and transcriptional silencing of tumor suppressor genes (TSGs) or other tumor-related genes in colorectal cancer (CRC) cells (PubMed : 24623306). Required to maintain a transcriptionally repressive state of genes in undifferentiated embryonic stem cells (ESCs) (PubMed : 24623306). In ESCs, in collaboration with SETDB1, is also required for H3K9me3 and silencing of endogenous and introduced retroviruses in a DNA-methylation independent-pathway (By similarity). Associates at promoter regions of tumor suppressor genes (TSGs) leading to their gene silencing (PubMed : 24623306). The SETDB1-TRIM28-ZNF274 complex may play a role in recruiting ATRX to the 3'-exons of zinc-finger coding genes with atypical chromatin signatures to establish or maintain/protect H3K9me3 at these transcriptionally active regions (PubMed : 27029610).. (Microbial infection) Plays a critical role in the shutdown of lytic gene expression during the early stage of herpes virus 8 primary infection. This inhibition is mediated through interaction with herpes virus 8 protein LANA1.
