    basic FUNCTION
  • nuclear regulatory factor, implicated in cellular transformation, in part through its ability to regulate the epithelial-to-mesenchymal transition and metastasis
  • corepressor of estrogen receptor alpha (ESR1), and transcriptional activator of Breast Cancer Amplified Sequence 3 (BCAS3)
  • playing a role as an upstream modifier of SIX3, a direct stimulator of rhodopsin expression, thus revealing a putative role for the MTA1/SIX3/rhodopsin pathway in vertebrate eye
  • involved in regulating transcription and this may be accomplished by chromatin remodeling
  • may operate as a negative modifier of apoptosis by interacting with TP53 during gametogenesis
  • destabilizes RFWD2 by promoting its autoubiquitination, thus creating a tight feedback loop that regulates both MTA1 and RFWD2 protein stability
  • required for optimum DNA double-strand break repair after ionizing radiation
  • role in DNA double-strand break (DSB) repair, and having an integral role in the nucleosome remodeling and histone-deacetylase (NuRD) complexes
  • required for optimum DNA double-strand break repair after ionizing radiation
  • required for MYD88-dependent stimulation of NFKB signaling and expression of proinflammatory cytokines such as IL1B, MIP2, and TNF1
  • involved in regulation of MYD88 which may constitute at least one of the mechanisms by which MTA1 stimulates LPS-induced NFkB signaling in stimulated macrophages
  • TP53-independent function in DNA damage response via modulation of the CDKN1A-proliferating cell nuclear antigen pathway
  • in addition to its role in the repair of double strand breaks caused by ionizing radiation, MTA1 also participates in the UV-induced ATR-mediated DNA damage checkpoint pathway
  • integral component of the nucleosome remodeling and deacetylase complex, implicated in the ionizing radiation-induced DNA damage response
  • first upstream modifier of GNAI2 gene expression and promotes Ras signalling
  • seems to be an important upstream modifier of GNAI2 expression and, consequently, could influence the activation of the Ras pathway, at least in part
  • master chromatin modifier, regulating the expression of HMMR and, consequently, its function in breast cancer cell motility and invasiveness
  • upstream coactivator of HMMR and is needed for its expression and resulting functions in invasion and migration
  • role for MTA1 in maintenance of circadian rhythmicity through acting on the positive limb of the clock machinery
  • participate in the DNA damage response beyond its well-established roles in gene transcription
  • MTA1 promotes the proliferation of epithelial ovarian cancer cells by enhancing DNA repair
  • MTA1 plays an important role in Epithelial-to-mesenchymal transition (EMT) to promote metastasis via suppressing CDH1 expression, resulting in a poor prognosis in malignant pleural mesothelioma (MPM)
  • critical homeostatic role of MTA1, both as a target and as a component of the neuronal oxidative stress, in the regulation of acute neuronal responses against brain I/R damage
  • cytoplasmic translocation of MTA1 coregulator promotes de-repression of SGK1 transcription in hypoxic cancer cells
  • MTA1 potentially promoted pancreatic cancer metastasis via HIF1A/VEGF pathway
  • MTA1-S100A4-MYH9 axis exists in endothelial cells as a novel pathway in promoting tumor vascular formation
  • is a chromatin modifier and its expression is significantly associated with prognosis of many cancers
  • MTA1 coregulator regulates LDHA expression and function in breast cancer

    text proliferation and growth of cancer cells; regulator of transcription (by chromatin remodeling)
  • important role for MTA1-BCAS3 pathway in promoting cancerous phenotypes in breast tumor cells
  • putative role for the MTA1/SIX3/rhodopsin pathway in vertebrate eye
  • a component
  • component of the Mi-2/nucleosome remodeling and deacetylating (NURD) complex that contains both histone deacetylase and nucleosome remodeling activity
  • complexing with histone deacetylase to plays an important role in histone deacetylation, alteration of chromatin structure and transcriptional control
    small molecule
  • target of MYC
  • target of ITGB3BP (regulatory interactions between MTA1 and ITGB3BP might be important in modulating the sensitivity of breast cancer cells to estrogen)
  • interacting with SIX3 ( physically interacts with the SIX3 chromatin in a histone deacetylase-dependent manner, leading to transcriptional suppression of the SIX3 gene)
  • interacting with TP53 (controls the stability of TP53 protein and consequently may constitute a new upstream regulator of TP53 protein)
  • interacts directly with histone deacetylase 1 (HDAC1) and HDAC2
  • behaves as a co-repressor of the GNAI2 gene
  • role for MTA1 as an upstream coactivator of TH
  • transcriptionally stimulates expression of the hyaluronan-mediated motility receptor (HMMR) and consequently regulates cancer invasion and migratory function
  • target of TP53-mediated transrepression
  • novel function for poly(ADP-ribose)ylation of TP53 in the gene-specific regulation of the transcriptional mode of TP53 on the promoter of MTA1
  • RBBP4-MTA1 interaction is essential for the integration of RBBP7/RBBP4 into the NuRD complex
  • histone chaperone protein RBBP4, bind to the C-terminal tail of MTA1, and MTA1 recruits a second copy of RBBP4
  • MTA1 is a novel corepressor of serum and glucocorticoid-inducible kinase 1 (SGK1)
  • PRKD1 is an upstream regulatory kinase of MTA1
  • associations of SPEN with MTA1 (metastasis-associated 1), a member of the nucleosome remodeling complex with histone deacetylase activity, which might contribute to interactions of SPEN with chromatin
  • TRIM25 is the E3 ligase that interacts with and degrades MTA1 protein in normal liver cells, and TRIM25 ubiquitinates MTA1 at lysine 98 and degrades it normal liver cells
  • cytoplasmic MTA1, but not nuclear MTA1, was colocalized with S100A4, suggesting bthe involvement of MTA1 in S100A4 stability
  • interaction of MTA1 with MYC and recruitment of MTA1-MYC complex on to the LDHA promoter to regulate its transcription
